This clamp is a means of attaching either 100 or 220mm duct systems to 1 ½ and 2 inch ladder racks. It is attached to the rack by a plate and two screws, which clamp the rack between the plate and clamp body. Multiple holes provide vertical adjustment in 21mm increments. Use in conjunction with 220 and 100mm duct mounting brackets (Part No’s: TC1279-13 & TC1279-14).
