Long plate round with cylinder hole and spring loaded folding cover brass / stainless steel (304) distancing 75mm / 72mm for rim locks /mortises with cylinder | GSV-No. 3343 ZK

The long plate with cylinder hole and spring-loaded folding cover GSV-No. 3343 ZK is a technically engineered fitting designed for doors equipped with rim locks or mortise locks with cylinders. It is available in two high-quality materials: brass and stainless steel 304. Brass provides a classic aesthetic with high corrosion resistance and long-term durability, making it suitable for interior doors or traditional applications. Stainless steel 304 offers superior mechanical strength, excellent wear resistance, and outstanding performance in environments exposed to moisture or heavy use, making it ideal for commercial or exterior doors.

The plate features a precisely machined cylinder hole, ensuring a secure and exact fit for standard profile cylinders and smooth operation of the lock. Two distancing options are offered: 75 mm, suitable for both rim locks and mortise locks, and 72 mm, intended exclusively for mortise locks. This flexibility allows the plate to be adapted to different door and lock configurations with reliable alignment and functional accuracy.

A key feature of this model is the stainless steel spring-loaded folding cover, which protects the cylinder from splash water and environmental exposure. The cover opens easily during operation and automatically returns to its protective position, thereby extending the cylinder’s lifespan and maintaining functional reliability under demanding conditions.

The long, rounded design of the plate ensures even distribution of mechanical forces on the door surface, contributing to stable mounting and long-term durability. GSV-No. 3343 ZK combines precise engineering, robust materials, and effective cylinder protection, providing a technically sound and durable solution for modern door hardware in residential, commercial, and public buildings.
