Tab Tension Projection Screens

Quick Answer: A Tab Tension Projection Screen is a roll-down screen with tabs along both side edges of the fabric that run on cables, pulling the surface taut sideways when it is lowered. A tab tension projection screen combines the retractable convenience of a roller screen with the flatness of a fixed frame.

What the Tabs Do

An ordinary roller screen hangs from the top and is held down only by the weight of its bottom bar, so nothing pulls the edges outward. Over time the fabric can develop gentle waves or curled edges, which bend straight lines and distort text. On a tab-tensioned screen, small tabs attached along each side of the fabric link to tensioning cables that run from the case down to the bottom bar. As the screen descends, the cables pull the edges apart and the surface is stretched flat.

That flatness matters most for detailed content, such as spreadsheets, code, chemical structures, maps and graphs from data loggers, where a ripple shifts lines and makes small labels harder to read. Tab-tensioned screens are usually motorised, and they are often recessed into a ceiling so that nothing is visible when the screen is raised. The drive type, size and aspect ratio of this listing are not stated.

Where flatness is needed but the screen never has to retract, a fixed frame projection screen is the simpler alternative.

Where Flatness Pays Off

• Lecture theatres and seminar rooms showing detailed slides, formulae and spreadsheets.
• Computer and design labs where fine lines and small text must stay sharp.
• Boardrooms and auditoria where a ceiling-recessed screen should disappear when not used.
• Rooms with short-throw or high-resolution projectors, which reveal any ripple in the surface.

Specifications

Care & Handling

• Lower and raise the screen only through its control; never pull on the tabs or cables.
• Keep the side cable paths clear of blinds, trunking and furniture.
• If a tab comes out of its cable, stop the screen and have it refitted before the fabric tears.
• Dust the surface gently and do not press on the fabric, which is under tension.

Why Choose LabEquip

Tab-tensioned screens are chosen for college lecture theatres, auditoria and boardrooms where both a clean ceiling and a flat image matter. LabEquip lists them in the General Lab Products range; share the room plan and projector details on the contact page.

Frequently Asked Questions

What is the difference between a tab tension screen and a standard roller screen?

Both roll down from a case, but a tab tension screen has tabs along its side edges linked to cables that pull the fabric sideways. This keeps the surface flat, whereas a standard roller screen can develop waves and curled edges.

Are tab tension screens motorised?

They usually are, because the side tension runs most evenly with the steady, even movement of a motor, and ceiling-recessed installations need remote operation anyway. Manual tab-tensioned screens exist but are less common.

Why does screen flatness matter for projection?

A wave in the fabric bends straight lines and shifts parts of the image slightly, so text and thin lines look uneven. The effect is most visible with high-resolution and short-throw projectors, which strike the screen at a steep angle.

Can a tab tension screen be recessed into a ceiling?

Many are designed for recessed mounting, so the case is hidden above the ceiling and only a slot is visible. This needs planning with the ceiling contractor and an electrician.

What should I do if a tab comes off the cable?

Stop using the screen and have it refitted. Running the screen with a loose tab can crease or tear the fabric edge.

Is a tab tension screen worth it for an ordinary classroom?

In a classroom showing mostly large text, pictures and video, a standard roller screen is usually adequate. Tab tension pays off where detailed content is shown regularly and the screen must retract.
