The Stainless Steel (303) Mounting Collar for 1" Pipe - Two-Piece Clamp Stackable (Cap) is designed to mount pipes or tubes securely to components, with bores sized to match the outside diameter of standard pipe. Its two-piece construction completely separates for easy installation and can be placed or repositioned anywhere along the pipe or tube. The collars feature flats with drilled and tapped holes for secure attachment and a countersunk mounting hole for fastening to a surface or hanging from a threaded rod. The stackable design allows multiple collars to be combined for flexible mounting configurations, while the precision-machined, non-marring construction provides secure clamping and easy adjustment. Available in Regular Stackable and Stackable (Cap) styles, the Regular version has flats on two surfaces for stacking, while the Cap version has a single flat to provide a finished, rounded outside surface when no additional stacking is required. Each collar is supplied with a mounting screw. This pipe mounting collar is available in both steel and stainless steel.
