Description
The Yale 3531T 689 is a heavy-duty surface-mounted door closer designed for commercial and institutional buildings that demand reliability and durability. Built with a cast aluminum body and rack-and-pinion mechanism, it handles high-traffic entries while maintaining precise control over door closing speed, latch action, and backcheck force. Non-handed design suits retrofit and new construction equally.
Compatible with regular arm, top jamb, and parallel arm mounting (tri-packed configuration). Adjustable spring sizes 1-6 allow fine-tuning to your door weight and application.
