Designed for frameless shower doors, this top bracket roller assembly set includes four pieces and an adjustable bracket with diagonal mounting slots that accept glass panels up to 3/16 inch thick. Constructed from chrome plated aluminum, the top brackets offer durability and corrosion resistance while maintaining a lightweight profile. The assembly clamps to the top edge of the shower door glass with a vinyl gasket to prevent slipping and protect the glass. A 3/4 inch ball bearing roller is mounted on an aluminum bracket, ensuring the door sits level after installation. The hardware is designed for glass panels up to 3/16 inch thick, providing stable contact at the door top edge. Installation is straightforward: slide the roller along the diagonal slot to adjust height, then tighten the fastener for secure fit. If needed, apply silicone adhesive to prevent movement and reduce risk of glass damage during operation in daily use cycles. Once installed, the roller system promotes smooth operation with a snug fit and minimal risk of glass damage, supporting steady movement during showers and reducing maintenance concerns. This setup is suitable for standard frameless shower enclosures where consistent alignment and gentle contact with the glass are important. Color: Silver.
