Guard Security Promag II 200 Brass Tubular Rim

The Guard Security Promag II 200 is a brass solid tubular rim cylinder designed for residential and light commercial doors. It provides a direct replacement or new installation option for standard rim nightlatch fittings. The unit is sold individually and includes four tubular keys.

Seven-pin tubular mechanism

This cylinder uses a seven-pin tubular keyway that resists picking and drilling more effectively than standard pin-tumbler designs. The brass body adds corrosion resistance for exterior use. Buyers needing a different pin count, a euro-profile cylinder or a mortice lock body will need a different product.
