China Heavy Duty Door Closer For Steel Doors Manufacturers – D71 SERIES CONCEALED CAM ACTION SIZE 3-6 DOOR CLOSERS – Dorrenhaus Detail:

Recommended for interior or exterior doors including:
• Offices
• Banks
• Retail Malls
• Hotels
• Health Care
• Clinics

Concealed door closers come in two main types: overhead concealed and under the floor concealed.

Concealed fire door closers provide the functionality of an overhead door closer but are fitted within the door leaf and frame. This type of installation is aesthetically pleasing and helps to reduce vandalism, as most of the door closer is hidden from sight.

Insert the retainer between the chain links closest to the cylinder face plate. Remove the anchor plate from the door frame and turn the anchor plate clockwise to increase the tension and anti- clockwise to decrease the tension. Re-fix the anchor plate to the door frame and remove the retainer.
