Degree of Opening<\/strong>:
\n\u2022 An integral positive stop limits door swing to 105\u00b0. The purpose of this stop is to prevent the door from hitting a wall or other architectural feature.<\/p>\n

Header\/Overhead Door Stops:<\/strong><\/p>\n

\"Ives<\/a>\"Don-Jo<\/a><\/strong>\"Dorma<\/a>\"Ives<\/a><\/strong><\/p>\n

\u2022 An auxiliary stop(Header Stop) should always be installed in conjunction with RTS88 to prevent a door from swinging past the required stop point.
\n\u2022 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\u00b0 degrees to clear the opening of protruding hardware<\/p>\n

Technical Details:<\/strong>
\n\u2022 A pressure relief valve protects closer from damage caused by forced closing.
\n\u2022 A mechanical backcheck slows down the door prior to contact with the positive stop.
\n\u2022 Closing speeds are controlled by two non-critical adjustment valves. Sweep area is from 105\u00b0 to 20\u00b0. Latch area is from 20 to 0.
\n\u2022 Thermostatic valves insure constant closing speeds under varying temperatures.
\n\u2022 The standard RTS-88 is furnished without hold open. Optional single point mechanical hold open is available at 90\u00b0 or 105\u00b0
\n\u2022 The RTS88 BFI and RTS 88 BFE are available in 105\u00b0 NHO
\n\u2022 The RTS88 offers a cast-iron body along with heavy-duty ball bearings at the spindle.
\n\u2022 Steel cam and roller assembly is coupled to dual steel pistons.
\n\u2022 Mounting brackets are available to install closer into aluminum or wood headers.
\n\u2022 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.
\n\u2022 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.
\n\u2022 No. 8521E add-on spindle extension is available for special applications where additional clearance is required between the closer body and the door.
\n\u2022 Cover plates are available for virtually any type header material.<\/p>\n
