L-400 Spring Bolt Lock Steel 400mm White Zinc Plated

Product Overview

The Zasuwa sprężynowa L-400 is a spring bolt lock designed for secure door closing in residential, industrial, and commercial settings. Constructed from durable steel with a white zinc coating, the bolt is highly resistant to corrosion and can be used in both indoor and outdoor environments, including for doors exposed to challenging weather conditions. Its robust automatic locking mechanism enhances user convenience and increases security for high-traffic or utilitarian doors.

A distinguishing feature of the Zasuwa sprężynowa L-400 is its 400 mm length, which allows for installation on larger or heavier doors and gates that require extended bolt reach and greater holding force. This makes it a practical solution in scenarios where standard-length bolts may not suffice, reducing the need for custom fabrication or additional reinforcement. The product is particularly well-suited for procurement by facility maintenance teams, gate manufacturers, or construction operations handling a variety of access points with varying dimensions.
