Pipe clamp

The Caddy Microfix easy-close pipe clamp can be used with either iron pipe or copper tubing. Its hinged design eliminates the need to disassemble the clamp prior to installation. A setscrew catches in a locking plate, eliminating the need for tools to position pipe in the clamp. Final tightening can be completed with one hand or a screwdriver.

Round fire/smoke damper

FSDR25 is a “true round” fire/smoke damper that can be installed in metal- or wood-stud walls and concrete floors. It is equipped with retaining “cinch” plates that make installation quick and easy. As with other Ruskin fire/smoke dampers, it can be installed with the plate on only one side of the wall.
