Swing Functions:
• Closing speeds are controlled by two non-critical adjustment valves. Sweep area is from 105° to 20°. Latch area is from 20 to 0.
• A mechanical backcheck slows down the door prior to contact with the positive stop.

Degree of Opening:
• An integral positive stop limits door swing to 105°. The purpose of this stop is to prevent the door from hitting a wall or other architectural feature.

Header/Overhead Door Stops:

• An auxiliary stop(Header Stop) should always be installed in conjunction with RTS88 to prevent a door from swinging past the required stop point.
• Door hardware may require that a door swing to only 85 degrees to prevent exterior handles from hitting a wall. Similarly, hardware on the push side of the door may require that the door swing further than 90° degrees to clear the opening of protruding hardware

Technical Details:
• A pressure relief valve protects closer from damage caused by forced closing.
• A mechanical backcheck slows down the door prior to contact with the positive stop.
• Closing speeds are controlled by two non-critical adjustment valves. Sweep area is from 105° to 20°. Latch area is from 20 to 0.
• Thermostatic valves insure constant closing speeds under varying temperatures.
• The standard RTS-88 is furnished without hold open. Optional single point mechanical hold open is available at 90° or 105°
• The RTS88 BFI and RTS 88 BFE are available in 105° NHO
• The RTS88 offers a cast-iron body along with heavy-duty ball bearings at the spindle.
• Steel cam and roller assembly is coupled to dual steel pistons.
• Mounting brackets are available to install closer into aluminum or wood headers.
• Packages are available for side load, end load, and offset slide arm applications. For independently hung doors with 8812 slide arm, the maximum degree of opening and hold open angle may vary slightly.
• No. 8532 steel header mounting channel is specifically designed to install the RTS series closer into open-throat steel header sections. Normally, the mounting channel is installed in the header prior to shipment to the job site.
• No. 8521E add-on spindle extension is available for special applications where additional clearance is required between the closer body and the door.
• Cover plates are available for virtually any type header material.

Certifications:
• The RTS88 is manufactured to conform with the requirements of ANSI A156.4.
