CLAMP for MODULE CONNECTIONS
Specially designed clamps provide a quick and easy assembly or disassembly of
MD3 modules. Two allen-head bolts quickly tighten or loosen the clamp using a
5/32 or 4mm hex key. The clamp contains a plate carrying two O-rings to provide
positive sealing between modules. Order clamp by part number R-A118-105.
Combined clamp and bracket (below) can be ordered by part number R-A118-105M.
MOUNTING BRACKET
Two brackets are normally used to mount an FRL to a vertical surface. The mounting
bracket attaches to the module-connecting clamp (see above) with a single screw.
Each bracket then employs two bolts (1/4” or 6mm) to connect the assembly to the
mounting surface. Order bracket and screw by part number R-A118-103. Combined
bracket and
clamp (above) can be ordered by part number R-A118-105M.
