C.R. LAURENCE DL2230 CRL Threshold Bolt Kit for 34" to 37" Cylinder Height
Adding the CRL Threshold Bolt Kit to a CRL DL2110 or DL2130 Deadlock allows maximum security for pairs of doors by the turn of a key. By simultaneously dropping a hardened steel hex bolt into the threshold, and pivoting the Deadlock Throw Bolt into the mating door's stile, the two-point lock secures the entire double door entrance.
