Prime-Line U 9858 Sliding Patio Door Lock Pin – 2-5/8" Chrome-Plated, Case-Hardened Steel, Secures Door In Closed Or Ventilated Position

About This Product

If your sliding patio door doesn't have a secondary lock, this Prime-Line lock pin adds an extra layer of security without a big installation hassle.

It's made from case-hardened steel with a chrome-plated finish that resists rust and looks clean.

The pin is 2-5/8 inches long, and it can be used to lock the door either fully closed or in a slightly ventilated position – perfect for getting some fresh air while still keeping the door secured.

When it's not engaged, the pin stores in its holder so you don't lose it.
To lock it, you just slide the pin into the retaining ring.

It also prevents the door from being lifted off its track, which is a common break-in method for sliding doors.
Installation requires drilling a 1/8-inch hole through the window frame and the fixed panel frame – simple enough for a DIY project with basic tools.

This is a cheap, effective way to improve the security of your patio door without replacing the whole lock system.

It's ideal for apartments, rental units, or homeowners who want a little extra peace of mind.

Solid construction, easy to use, and it does exactly what it's supposed to do – keep your door where it belongs.
