Surface Mount Fire Door Closer

A robust, surface-mounted spring door closer designed for compliance-ready installation on fire doors and standard interior doors. Built with aluminium alloy casing, stainless steel moving parts, and zinc alloy mounting brackets using integrated moulding and multi-channel assembly techniques. Supports doors weighing 20–39.9 kg and up to 1000 mm wide, with full 175° opening capability. Spring tension is manually adjustable via included hex wrench — enabling precise control over closing speed (non-damped), suitable for both left- and right-hand doors. Ideal for UK homes, flats, offices and small retail units where reliable, low-maintenance door control is required without hydraulic complexity or certification overhead.
