Master Lock Co 270D Folding Door Security Bar

Product Description

The MASTER LOCK CO 270D is a folding door security bar designed to brace both sliding and hinged doors against forced entry. The bar features a quick-release hinge mechanism that allows it to unfold and adjust rapidly to fit a range of door configurations. When not in use, the folding design reduces the stored footprint, making the bar practical for job sites, rental properties, or portable security applications. At 9.4 pounds, it delivers solid resistance without being difficult to handle or transport. Security professionals, property managers, and facility maintenance technicians are the primary installers of this type of hardware.

The 270D is suited for residential and light commercial applications where temporary or semi-permanent door security is needed. Its adjustable length allows it to fit standard hinged interior and exterior doors as well as sliding patio and glass doors. The compact folded profile makes it easy to carry between locations, store in a tool bag, or deploy quickly during a service call.

Installation Notes

Installation is typically performed by a general contractor, property maintenance technician, or security professional. No power tools are required for standard deployment. Confirm the floor surface is solid and level before setting the bar, as soft or uneven flooring can reduce bracing effectiveness. Remove the bar completely before opening the door to avoid damage to the floor or door frame.
