## About this knob

The CRL Square Ribbed Back-to-Back Knob 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 2 finishes, including brushed nickel, matte black.

This square knob is shaped to match square-cornered shower door hinges, and its ribbed design adds an attractive, finished look. It's solid brass, measures 1-3/16" across and stands 1-3/16" from the surface of the glass. It mounts back to back, so you get a knob on both the inside and outside of the door. It fits glass from 1/4" to 1/2" thick and needs a single 1/2" hole in the glass.

- 1-3/16" (30 mm) square, 1-3/16" (30 mm) from the glass
- Square shape matches square-cornered hinges
- Attractive ribbed design, solid brass
- Fits 1/4" to 1/2" (6 to 12 mm) tempered glass; needs a 1/2" (12 mm) hole

### Match your holes, glass and finish.

Measure center to center between your existing holes and check your glass thickness. A new handle has to match both.
