Quick-to-install lock set for thinner interior or exterior doors. Ideal for thinner exterior doors, the Perko Rim Lock Set provides the added security of a dead bolt with a surface-mounted design that makes installation quick and straightforward. The exterior features a chrome-plated escutcheon plate that adds a sleek, polished finish to the knob and locking mechanism. The interior assembly houses the latch and dead bolt components. Its larger surface-mounted design helps distribute the load over a wider area, increasing holding strength for reliable protection. The interior lever operates smoothly and locks with a simple twist of a button. At the same time, the exterior knob allows secure access with a key, combining convenience with security for every entry point. Built to withstand marine environments, all exposed metal surfaces are chrome-plated for superior corrosion resistance, ensuring long-lasting performance. The Perko Rim Lock Set is compatible with both right-hand and left-hand doors, eliminating the need for disassembly, and works with doors ranging from 5/8" to 1 3/8" thick. A mounting template simplifies installation by accurately locating the hole for the shaft pass-through. Made in the USA, this lock set offers dependable marine-grade construction, enhanced security, and a refined appearance, making it the perfect upgrade for exterior doors on boats or other settings where strength and style are essential.
