CRL Oil Rubbed Bronze Shower Door Knob - Cylinder Style Back-to-Back Design for Bathroom & Shower Enclosure Installation

As advertised. Very nice knob, feels solid, surprisingly very heavy. Good quality. I used this knob on a sliding glass shower door. The knob matched really well with the other fixtures in the bathroom.This knob has two identical sides, both with female threaded opening. I split the knobs and used them on 2 different holes in the inside side of the inner sliding glass shower door. This knob set came with 2 clear washers and a 40 mm length, 1/4 inch diameter threaded bolt which is removable from both knobs. To spilt the knobs and used in two different holes, I removed the towel bar style handle bar but used the existing 1/4 inch diameter 20mm length screw/bolt and clear rubber washers that came with the shower door. I didn't want to use the original towel bar because it took up too much space in the shower/tub area and also didn't want someone using the towel bar for bracing purposes as the sliding glass door is not structurally sound to use for that purpose.The diameter of the cylinder style knob is 18-19 mm about the same size as a penny.There are other options on Amazon to purchase the same style CRL knob that comes with the decorative side male screw/bolt and 2 washers but was $17.00 for a single knob, which meant I would have needed to order 2 for $34.00. Since I already had the 2 original decorative male screw/bolt and 4 washers that fit these CRL knobs, I was able to order these knobs for $13.00. 5 stars ⭐️⭐️⭐️⭐️⭐️ for quality, style and price.
