Summary: The Perpendicular Collar for 1.67-inch OD Tubing (818/424) is a perpendicular collar for 1.67-inch pipe handrail from Lavi Industries. It seats into the end of a 42.4 mm tube for a flush fit and receives a second tube at 90 degrees. Full rotation around the main tube lets the branch be set exactly where the layout needs it before it is fixed. It fits Schedule 40 pipe with .080-inch wall. It is made in 316-grade stainless steel, polished or satin, for coastal, washdown, and marine installations. It pairs with the 1.67-inch tubing, splices, and fittings in the 316 family. Ships from US inventory.

Perpendicular Collar for 1.67-inch OD Tubing
Full rotation solves the placement problem: the 818-424 slides into a 1.67" OD (42.4mm) pipe-handrail end for a flush fit, then turns around the main tube until the secondary run lands exactly where the layout needs its 90° branch. 316 Polished or Satin — marine-grade marine-grade for the 42.4mm pipe standard.
