Can lock hardware be added to a frameless glass cellar door after installation?

Not once the glass has been tempered. Tempered glass has to be cut, drilled, or notched before the tempering process, because it cannot be reworked afterward without the pane failing. Any hole for a lock cylinder, a strike, or a mounting plate on a glass leaf has to be decided and cut into the design before the glass goes into the tempering oven, which is why lock hardware for a glass door gets specified early rather than added on site.

Are wine lockers in a restaurant or club program secured individually?

Yes. Club, restaurant, and hotel locker programs are offered with lock tiers alongside zoned climate control, so a single locker can be locked to one member or guest without changing the climate conditions shared by the rest of the room. The lock and the climate zone are specified as separate systems even though they sit in the same cabinet.

Does hardware choice matter differently for a restaurant cellar than a home cellar?

It adds a second requirement. Commercial installations have to balance sommelier retrieval speed against front-of-house display, since the same door a server needs to open quickly during service is often the door guests see from the dining room. Hardware fast enough for staff still has to read correctly on a cellar built to be looked at, which a private residential cellar does not have to consider.

Does the wall or ceiling around the door make up for hardware penetrations in the leaf?

No, because that insulation number belongs to a different assembly. Cellar walls are specified to a minimum of R-19 and ceilings to R-30 or higher, but that figure describes the wall and ceiling construction, not the door. A lock bore or a keypad penetration in the leaf is a separate detail that the surrounding wall's insulation value does not offset.

Can a door frame be custom-built to fit hardware in a non-standard position?

Yes. Specialty doors are available through trade and wholesale supply channels that include custom frame options, which lets a frame be built with hardware positioned relative to the gasket line and the frame's own members rather than forcing a lock or a reader into a standard frame not designed for it.

Does a lock or keypad penetration get accounted for in the cooling load?

Not as a line of its own. Cellar cooling is specified from a heat load calculation rather than from square footage, and that calculation takes the door assembly and how often the door opens as inputs. A bore through the leaf or a back box behind a keypad is too small to appear as a separate term in it, which is why a hardware penetration has to be resolved at the seal detail rather than absorbed later by equipment capacity.

Wine Cellar Door Hardware and the Seal Line It Crosses

Choosing Between Them for a Specific Run

Once a schedule has been issued to anyone, changing a value quietly is worse than not changing it. A revised schedule carries a new revision number, a new date, and a marker against every row that moved, so a reader holding both versions can tell in seconds which lines are different. Reissuing a corrected sheet with no revision marker leaves two documents in circulation that look interchangeable and are not.

The reissue also has to reach the people working from the old one. A cellar's fixture order, the racking shop drawings, and the electrical rough-in can all be running from the same schedule at the same time, and a Kelvin value corrected on the designer's copy changes nothing until the version carrying that correction lands with whoever placed the order.

Fixture substitutions happen at bid, at order, and occasionally after delivery, and a fully populated schedule is what sets the terms of one in advance. A substitution proposed against a complete row has to hold every value on that row, including the ones a supplier would find inconvenient to match. A fixture matching wattage, beam angle, and trim size while dropping below a stated CRI floor is a different specification, and a populated row makes that visible without an argument about intent.

The burden of showing it sits with whoever proposes the swap. A substitution request arriving as a catalog number and a price, with no line-by-line comparison against the scheduled values, has not been made yet; it has been asked about. Requiring that comparison in writing is what keeps the substitution a decision the specifying professional is still making.

The Sheet Has to Say What It Is

TIP: A schedule reissued after fixtures are ordered should say so on the sheet. A revision that arrives post-order is a change order in practice, and marking it as one keeps the cost conversation attached to the line that caused it.

New Title

Every piece of hardware on a cellar door is a hole in something that was supposed to run unbroken. A mortise lock is a pocket cut into the leaf. A lockset bore is a straight path from one face to the other. A magnetic lock needs a strike mounted at the jamb and a wire reaching it. A keypad or reader sits on a face that stays humid for the life of the door. Handles and pulls are fastened through, not applied on top. Each of those is a legitimate requirement on a serious collection, and each one lands somewhere specific relative to the seal line the door exists to hold. Hardware gets specified for how it looks and how it locks. It is rarely specified for what it does to the gasket, which is the part of the door actually doing the work.

A mortise lock body sits inside a pocket routed into the edge of the leaf, deep enough to hold the case and the latch mechanism. On a solid wood or an insulated metal leaf, that pocket removes material from the same cross-section that is supposed to run edge to edge without a gap. A bore-and-latch lockset is a different kind of cut: a hole straight through the leaf, face to face, sized for the cylinder and the spindle. Both are legitimate, and both have to be sealed and finished as carefully as the rest of the door, not treated as a fixture bolted on after the leaf is complete.

A frameless door's seal is a magnetic gasket that runs continuously along the jambs and the head, with no perimeter frame breaking that line. A strike plate for a lock has to mount somewhere on that same jamb, and if it lands inside the band the gasket needs to contact, it creates a small step where the magnetic strip cannot press flush against the frame. That step is not large, but it sits at exactly the height a walk-through rarely checks, since attention goes to the swing and the latch feel rather than the narrow band of jamb behind the strike.

On a wood or metal door with a mechanical latch, the interruption runs the other way. A strike mortise is cut into the jamb at latch height so the bolt can reach it, and that cut crosses whatever weatherstripping or compression seal was specified to run along that same jamb. The latch needs depth to engage; the gasket needs a continuous surface to compress against. Those two requirements occupy the same few inches of jamb, and one of them gives unless the hardware position and the seal detail are drawn together instead of specified separately.

A keypad, a card reader, or an electronic strike mounted on the interior face of a cellar door lives at whatever humidity the room is built to hold, day after day, as a constant operating condition rather than an occasional exposure. That is a different service condition than the same hardware would see on an exterior gate or an office door. Access hardware of that kind usually reaches a cellar door through a security or low-voltage supplier working to its own specification, and the component ratings are that supplier's call. What the cellar side owns is the detail around it: where the unit lands relative to the gasket, how its back box passes through the leaf or the frame, and how that opening gets sealed and finished afterward.

The back box behind that keypad is its own penetration, separate from the lock body lower on the door. It has to pass through the leaf or the frame to reach whatever it is wired to, and that hole needs the same attention to sealing and finish as the lock bore does. Skipping that step because the keypad reads as a small, low-profile fixture is how a second, smaller leak gets added next to the one everyone already planned for.

Handles and pulls are fastened through the leaf, face to face, not applied as surface decoration. On an insulated metal door with a thermal break running through its cross-section, an unplanned through-fastener can bridge that break directly, connecting the inside face to the outside face with a short length of metal that the thermal break was built to interrupt. A single fastener rarely undoes the whole assembly, but it is still a path the design did not intend, added at the point where the hardware supplier and the door fabricator hand off to each other and neither one owns the detail.

On a sealed wood leaf, the same through-bolt penetrates a finish that was specified to keep water out of the wood, and the hole needs its own seal where the fastener meets that coating, distinct from the finish itself. Left alone, that single point is where the finish fails first, well before the broad face of the door shows any wear.

Every hardware item on a cellar door carries two specifications at once: what it looks like and how it locks, and what it does to the seal that surrounds it. The first gets asked constantly, in finish samples and lock-style catalogs. The second rarely gets asked at all, because it requires looking at a lock, a keypad, or a handle as a hole first and a fixture second.

Where each item lands relative to the seal, and what happens to the gasket at that exact point, is a different answer for every item on the list. A mortise lock takes material out of the leaf's edge. A magnetic strike takes a mounting position off the jamb the gasket needs. A keypad adds a back box behind the face; a plain handle adds two through-bolts and nothing else. Settling that for each item during design, while the leaf is still a drawing and the frame is still a set of dimensions, costs nothing but a conversation. Settling it after the door is built costs a second visit, a second cut, and a seal that now has to work around a decision instead of alongside it.
