A screen that is only there when it matters

Floor, ceiling, foot-of-bed, behind-art and counter lifts. The mechanism is chosen against the screen weight and the real opening, the cabinet is built in the shop, and the wiring and the finish work come with it.

Configurations

Where the screen goes when it is gone

Five arrangements cover almost every residential job. The choice is usually made by the room, not by preference.

A Travel 24–48 in · screen to 85 in

Out of a cabinet or console

The common one. A column lift inside a case, screen rising out through a lid that opens on the same cycle. Sits against a wall or in the middle of a room as a divider. Needs case depth, a stable base and a lid mechanism that never fights the column.

B Drop 12–48 in · needs 8–14 in of depth

Down from the ceiling

A drop-down or flip-down lift in the joist space, closing to a flush ceiling panel. The hard part is not the lift — it is the closure, the joist framing and getting the panel to sit flat in a ceiling that is not flat.

C Travel 20–40 in · screen to 65 in

At the foot of the bed

A lift built into a bench, blanket chest or bed footboard. Height matters more than anywhere else — the top of the screen has to clear the mattress without dominating the room when it is up.

D Art weight to 90 lb · lateral or roll-up

Behind art

The artwork slides, rolls or pivots aside on cue and the screen is behind it. The mechanism is straightforward; the coordination is not, because the art has to be handled, weighed, and often reframed to sit in the carrier.

E Travel 14–28 in · screen to 43 in

Up from a counter or island

A short-travel pop-up in a kitchen island, bar or built-in desk. Usually the tightest of the five, because the cabinet is already full of something else and the countertop cut has to be exact.

Selection

Five numbers pick the mechanism

Not the brochure, and not what is in stock. These get measured or confirmed before anything is quoted.

Screen weight and size
The published capacity of a lift is not the number to design to. Panel weight, mount weight, cable weight and any art carrier all land on the same column.
Available travel
How far the screen has to move to be genuinely out of sight, measured in the room rather than assumed from the drawing.
What it mounts to
Slab, joist, stud bay, or a cabinet carcass that has to be built stiff enough to take the reaction load without racking.
Noise floor
A quiet room makes a mediocre motor obvious. Screw-drive columns, belt drives and rack systems all sound different, and the mounting is half the noise.
Control path
Whether it needs to answer to a control system, a wall keypad, a dry contact from the projector, or just a handset that will not get lost.

Independence

I am not anyone's dealer

Auton, Nexus 21, Future Automation and Firgelli all make mechanisms I have specified and installed. They are good at different things and they fail in different ways, and none of them is the right answer to every opening.

What that means in practice: the quote names the mechanism, the model number and why it was chosen, along with the option I did not pick and what it would have cost. If you would rather buy the mechanism yourself at your own trade pricing, that is fine — I will install it.

Questions

Asked before every job

Either. If you have already bought the mechanism, I will install it as a subcontract and tell you honestly if I think it is wrong for the opening before anything gets cut. If I am supplying, I will show you two options with the reasoning and the price difference.

A straight install into existing millwork is usually one day, plus a short return visit to adjust after the house has moved a little. A shop-built cabinet with a mechanism in it is typically two to four weeks from approved drawing to installed, most of which is shop time rather than site time.

Between roughly half an inch and one and a half inches per second, depending on the mechanism. That feels slow the first time you see it. It is meant to — speed is what cheap mechanisms use to seem impressive, and it is also what makes them loud.

Every build gets a manual override and an access path that does not involve demolition. I keep the mechanism model, the serial number and the wiring notes on file, and column lifts from the manufacturers I use are still serviceable well beyond their warranty.

Often, yes. A cabinet lift usually can. A ceiling lift depends entirely on joist direction and what is already in the bay, which is a measurement question rather than an opinion — I will come and find out before quoting.

Next step

Send the screen model and a photo of the wall

That plus a rough ceiling height is usually enough for a mechanism recommendation and a range. Drawings and finish schedules welcome but not required.
