CLRL/CLR suspension rings are two-piece circular clamps.
One of the fastening lug pairs is latched in the suspension rings of up to 400 mm in diameter to increase the ease of clamping around the ventilation duct.
Suspension rings in this diameter range are installed with an M8/M10 (CLRL-K/CLR-K only M8) rivet nut on a threaded rod or a stud bolt.
Suspension rings in the diameter range d < 450 mm need to be fastened with two threaded rods. As a result, rivet nuts are not required for these product sizes.
