Don-jo AST21346WH Double Hole Door Strike 18 in White

Product Description

The DON-JO AST21346WH is a double hole door strike designed for doors with 5.5-inch and 6-inch backset centers. Measuring 1.75 inches wide by 18 inches long and 0.38 inches thick, this strike plate provides a flush, low-profile fit in standard door frame mortises. The white finish suits painted hollow metal or wood door frames in commercial and residential applications. Licensed locksmiths, door hardware installers, and general contractors install this type of hardware during new door assembly or replacement service calls. It is sold individually and available in case quantities of 10.

This strike is suited for use in commercial or residential door applications where dual-hole alignment is required for 5.5-inch and 6-inch latch or deadbolt center spacing. The 18-inch length accommodates extended frame coverage common in hollow metal door frames, multi-point locking systems, and institutional door installations where a longer strike is required for code compliance or added door security. Installers select this length when shorter standard strikes do not adequately cover the door frame cutout.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware installer. The door frame and any associated locking hardware must be de-energized or mechanically disengaged before strike removal or installation. Standard installation requires a chisel, drill, and appropriate fasteners for the frame material. Verify mortise depth and frame preparation match the strike dimensions before final fastening.
