Designed from the ground up to present glass panels by grasping the top edge of the panel via a through-hole. However, Top Clamps are not limited to glass panels as all sorts of materials may be professionally presented in the same manner.
A cable, supported above by a pier or track, is brought down to the desired 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 panel or glass lite is brought 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 protect the glass from the metallic screw. The design of this fitting is optimized for suspending glass in a vertical orientation.
It is also possible to connect another 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 and hold the entire assembly in tension. This would be accomplished by use of Fixed Piers or Classic Ceiling Track and Cable Tensioners. The Classic 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 surfaces. 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.
We offer Top Clamps in small, medium and large sizes. The small size is compatible with monolithic glass sheet of 5/32” (4 mm) and 3/16” (5 mm) thick glass. The same would be true where you would use the supplied bushings to protect the panel of some other easy to chip substrate. When bushings are not required, this small Top Clamp is compatible with panels of most any substrate up to 9/32" (7.15 mm) thick.
The medium sized Top Clamp is compatible with 1/4” (6 mm) monolithic glass sheet. These measurements also would apply to other substrates where you would choose to use bushings to protect the panel. When bushings are not required, this medium Top Clamp is compatible with panels of most any substrate up to 5/16" (8.0 mm) thick. See downloadable documents below, for more compatibility dimensions.
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 large 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.
All supplied screws are made of stainless steel for years of service with no maintenance issues.
