Summary: The Undrilled Wall Flange for 1-Inch OD Tubing (500U/1) is an undrilled wall flange from Lavi Industries for 1-inch railing tubing. It shares the 2-inch base and 7/8-inch projection of the drilled 500/1, but it has no holes at all, in the base or in the neck. The installer drills the base to the pattern the job needs and drills the neck for the set screw that locks the tube. The base can also be bonded with structural adhesive, so no fasteners show on a finished face. It is made in 304-grade stainless steel, polished or satin, for interior runs. It is used for concealed-fastener accent rails, display rails, and closet or shower rod mounts. It pairs with the 1-inch tubing, end caps, and brackets in the same line and ships from US inventory.
