Before installing bulk pack BK-1135 John Sterling Window Guards, use locking channels to convert to swing open egressguards. For security, add a padlock or lock pin in the hole. Note: No
window guards are included. This is a locking channel only. Will NOT fit
the 1120 series of John Sterling Window Guards. Made in USA.
Use one channel with each 5 bar John Sterling window guard at the time of installation. Each locking channel has a padlock hole to use for either a safety release pin (not included) or a padlock (not included).
