Union N8825 Heavy Duty Signature Door Closer

Larger picture

To complete UNION’s recently launched range of door closers, the N8825 offers a robust, heavy duty backcheck door closer.

Featuring three fully adjustable control valves, it is made from durable materials and CE marked, giving peace of mind. The adjustable backcheck helps to protect the immediate surroundings from damage. Its clean, smooth lines ensure that it will blend with both traditional and contemporary interiors.

The CE mark means this closer has been successfully tested to BS EN 1154. It has also been included in fire tests to BS EN 1634-1, with assessment for use on timber fire doors with intumescent protection up to FD 120. Factory production control audited by independent inspection bodies offers further reassurance that purchased products are identical to the tested models.
