It ships with a slim line cover and sex nut fasteners and features a rack-and-pinion hydraulic mechanism with valve-controlled backcheck. The aluminum alloy body keeps weight manageable while providing corrosion resistance suitable for interior and transitional door installations. Licensed door hardware technicians and commercial contractors handle typical installation. The unit weighs 8.7 pounds and has a finished aluminum appearance that blends with standard commercial door hardware.\u003c\/p\u003e\n\u003cp\u003eThis closer is suited for commercial building entrances, interior corridor doors, and office suite entries where a hold-open position is needed for traffic flow or ADA-compliant passage. The adjustable hold-open feature allows the door to remain open at a set position and release on demand or through an integrated trigger.
