Latch/Holder for Gate and Shutter UN model PDF4B, yellow, single piece

The UN PDF4B latch/holder is a compact mechanical device designed to hold gates and window shutters in position. Supplied as a single yellow piece, it provides a visible and simple manual retention point for both outdoor and indoor openings where a small, easy-to-operate retaining element is required. The product is intended for straightforward securing of doors, shutters or lightweight gate leaves and is compatible with installations that accept a surface-mounted style latch.

Advantages

This single-piece latch is immediately visible due to its yellow finish, which aids identification and operation. Its compact form factor allows installation in limited-space locations and on a variety of frame types. The mechanical design requires no power supply or electronics, making it reliable and low-maintenance for long-term holding functions. The product is supplied ready as a single unit for simple replacement or retrofit tasks.

Suitable for

• Holding garden or courtyard gates in a fixed open or closed position
• Securing exterior or interior window shutters
• Small service doors or access panels that require manual retention
• Retrofit projects where a visible, surface-mounted latch is preferred

How to use

Install the latch at a suitable height and position on the gate, shutter, or frame so that the retention point aligns with the corresponding catch or mounting surface. Secure the unit using appropriate fasteners for the substrate (screws or bolts not supplied). Engage the latch manually to hold the gate or shutter in the desired position and release it by operating the moving element to free the door. Periodically inspect the mounting and moving parts for wear and tighten fasteners as needed to maintain reliable operation.

Usage recommendations

For outdoor installations, use corrosion-resistant fasteners and consider routine lubrication of moving parts to extend service life. Confirm that the latch strength and mounting arrangement are appropriate for the weight and wind exposure of the gate or shutter. If precise dimensions or mounting hardware are required, consult measurement before purchase to ensure compatibility.
