The Hasp-Loc, made entirely of polycarbonate and stainless steel, is the easiest and fastest monkey secure cage lock available for small apertures. The Hasp-Loc serves also as a fast and secure alternate to Spring Snaps and Quick Links for enrichment devices. You can open this lock in less than 5 seconds using our Pin-Key or any other small diameter object such as a bent paper clip. When installed on the cage, this lock cannot be opened without a tool, guaranteeing that your monkeys and enrichment devices stay put. The Pin-Key is inexpensive enough that everyone in your lab can have one. Because it is not attached to the cage, the Hasp-Loc Cage Lock can quickly follow enrichment devices and difficult-to-contain monkeys when changing cages.
