Top Clamp, Large

Top Clamp, Large

This is the largest of three items that are specifically designed to suspend panels and glass “lites” by their top edge and suspended from above. While the design of this product family is optimized for suspending monolithic glass in a vertical orientation, Top Clamps may be used with any number of substrates where the panels are prepared with through-holes.

From a pier or track, such as Ceiling Track, a cable is suspended and brought down to the desired elevation of the upper edge of a panel and inserted into the cable hole at the top of the Top Clamp. Two supplied set-screws are then tightened against the cable.

Next, a glass “lite” or graphics panel is raised to the clamp side of the Top Clamp. The clamp is equipped with a set-screw that must pass through the panel. Two bushings are supplied if glass is being suspended and to buffer the glass from the metallic screw.

We offer Top Clamps in small, medium and large sizes. This large size is compatible with monolithic glass sheet of 5/16” (8 mm) and 3/8” (10 mm). The same dimensions apply to any substrate where you prefer to use the supplied bushings to protect the panel from potential damage caused by contact with the metallic screw. When bushings are not required this Top Clamp is compatible with panels of most any substrate up to 1/2” (12.7 mm) thick. See downloadable documents below, for more compatibility dimensions.

It is also possible to invert and attach a second pair of Top Clamps to a second set of holes on the bottom edge of a display panel. Cables from these lower clamps can then continue to a lower fixed point to hold the assembly in tension. The lower end of the cables would be determined by the attachment at either of Fixed Piers or Ceiling Track and Cable Tensioners. A Ceiling Track would be inverted to be used in a lower position. In this way a room divider could be fashioned quite easily. Both sides of the panels could be finished and display material could be equally effective on both sides. Likewise, there could be a second panel below the upper one and both could be held in tension from a pair of cables. See Application Guide below.

All supplied screws are made of stainless steel for years of service with no maintenance issues.
