Top-Bottom Clamps

Top-Bottom Clamps

Top-Bottom Clamps do not interact with a cable – only with the two panels between which it attaches. These are a sister products for our Top Clamps. Like the Top Clamps, they are designed to present glass panels by grasping the top edge of the panel via a through-hole. Also similar to Top Clamps, they are not limited to glass panels as all sorts of materials may be professionally presented in the same manner.

At the bottom of a panel, simply attach a Top-Bottom Clamp to a set of prepared holes. Then you are ready to attach a second panel below the prior one.

The clamp is equipped with set-screws that must pass through the panels. Four 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 monolithic glass in a vertical orientation.

We offer Top-Bottom Clamps in small and medium sizes. This small size is compatible with monolithic glass sheet of 5/32” (4 mm) and 3/16” (5 mm) thick glass while the medium size, ¼” (6 mm). 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, the small and medium sized Top-Bottom Clamps are compatible with panels of most any substrate up to 9/32" (7.15 mm) and 5/16” (8.0 mm) thick, respectively. See downloadable documents below, for more compatibility dimensions.

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