About this knob

The CRL Cylinder Back-to-Back Knobs with Plastic Sleeve is a back-to-back knob for frameless glass shower doors that fits 1/4" to 1/2" glass. Made by C.R. Laurence (CRL) in 4 finishes, including polished chrome, brushed nickel, matte black.

These cylinder knobs add a simple, clean touch without taking attention away from an all-glass door. Each knob is 3/4" across and stands 1-1/4" off the glass, with one on each side of the door. The plastic sleeve protects the knob surface, which is why it's the go-to choice for sliding bypass shower doors. They're made of solid brass and fit glass from 1/4" to 1/2" thick. You'll need a single 3/8" or 1/2" hole through the glass.
