SECURITYMAN Door Security Bar — 2-in-1 Adjustable Iron Brace for Hinged & Sliding Doors, Black, Fits 18.25"–46.5", Rubber Feet

The SECURITYMAN 2-in-1 Door Security Bar is an adjustable, high-grade iron brace that secures hinged and sliding patio doors by resisting up to 400 pounds of force.

If you're looking to add a quick, visible layer of protection to interior or patio doors without drilling or complicated installation, this two-in-one security bar provides a sturdy, adjustable option. Built from heavy iron and finished in black, the bar fits a wide range of door sizes and locks into place beneath knobs or along sliding door tracks. Its rubberized feet protect flooring while creating a secure contact point that helps keep doors from being forced open.

How does this bar fit different door and knob types?

The SECURITYMAN bar slides to match common door widths and props beneath most knob styles, including round and lever handles as well as French door configurations. It also includes caps for sliding doors so you can retrofit it for patio tracks.

• Adjustable length: extends from 18.25" up to 46.50" for hinged doors.
• Sliding-door caps included; note caps reduce maximum extended length to 46.50".
• Angled rubber bottom conforms to hardwood, tile, laminate, and carpeted floors.
• Works with standard door knobs, levers, and some French door hardware.

How simple is it to install, adjust, and remove?
