The Adams-Rite style latch is the one in use in any aluminum framed door such as the one at your local 7-11 or any other retail shop. Use the Trip wire to trip the locking latch feature of the Adams-rite 4700 & the new 4900 series door hardware. Will independently open an Adams rite, we recommend the use of a Slim Jim or other tool to extend the wires life. Includes: 1 trip wire plus an Adams Rite Slim Jim. Detailed instructions are included.
