Precision Engineering for Concealed Hardware
- Type 17 & 17R Compatibility: This is the primary replacement screw for Rockwood’s concealed mounting sets. It is essential for securing the ends of 1" diameter bars where a clean, fastener-free appearance is required.
- Double Cone Head Design: The unique double-tapered head is designed to seat perfectly within the handle’s mounting bracket, providing a stable, non-wobble connection.
- Standard Duty Reliability: Engineered for standard commercial use, this Phillips head screw allows for easy installation and maintenance with common tools.
- Architectural Seamlessness: By utilizing a concealed mount, this screw helps achieve the "floating" handle look preferred in modern office buildings, retail storefronts, and high-end residential entries.
