Berna MightyHold© components

(pour le français, SVP cliquer sur le symbole FR situé en haut à droite) 

The components of a Berna MightyHold© are: an axis - a 2/5" diameter high density carbon fibers tube - equipped at each of its ends with a silicon stop - and a polycarbonate jaw that can slide on the axis. At its opposite end to the passage hole of the axis, the jaw is provided with a very springy silicon buffer, for contacting the objects. The Berna MightyHold© 1 has a 61/2 " long axis and its jaw depth is 4" long. The Berna MightyHold© 2 has a 61/2 " long axis too. But its jaw depth is 6" long. For replacing the basic 61/2 " long axis, axes that are respectively 10", 13", 20"  and 30" long are available. Also available is a coupling accessory named "MightyHold beam connector" to connect end to end these beams so that the Berna MightyHolds© span can be firmly and easily extended.

Materials that are used:
For each Berna MultiClamp© or MightyHold©, the clamp beam uses high-density carbon fibers that allow it to be light, strong and flexible. The jaws use the same type of polycarbonate used in bulletproof windows. The buffers at the end of the jaws are made with a type of silicone, which is springy enough to avoid damaging the work and to allow resistance to vibrations. Silicone is also heat resistant (it is normally used for oven gaskets). So Berna MultiClamps© and MightyHolds© may be used for soldering and welding, provided the flame is not constantly focused on the jaws and buffers. Hot-air guns will not harm the clamps.
 
 
Weight of the Berna MightyHolds©: about 2 oz.
 
Clamping force: the force with which your arms are pushing upon the jaws close to the beam in the direction of the clamped objects, i.e. zero up to over your own body weight, if you can to lift up your body when performing chinning bar exercises.
