The GEZE TS 500 NV floor spring is an industry-leading concealed door closer engineered for single and double-action doors up to 1100 mm in leaf width and 150 kg in weight. Ideal for heavy-traffic commercial environments, this highly durable mechanism is fully certified for use on fire and smoke protection doors.

Designed for maximum flexibility without the need for conversion, the GEZE TS 500 NV accommodates both right and left-hand doors seamlessly. The fully variable closing force (EN 1-4) and adjustable closing speed ensure precise access control. Its integrated mechanical back check protects both the door and the frame by slowing down doors that are thrown open forcefully.
