Prime-line MP9427 Combo Deadlatch Deadbolt Strike

Product Description

The PRIME-LINE MP9427 is a combination deadlatch and deadbolt strike plate designed for residential door hardware applications. Constructed from alloy steel with a brass plated finish, this strike provides a reinforced mounting point for both a deadlatch and a deadbolt in a single unit. It ships with six 3-inch screws that seat deep into the door frame for maximum pull-through resistance. The plate spans a hole spacing range of 3-5/8 inches to 4 inches, making it compatible with standard door jamb preparations. Licensed contractors and capable DIYers install this type of hardware during lock upgrades, door replacements, or jamb repairs.

This strike plate is suited for residential entry doors where both a spring latch and a deadbolt are present in the same door prep. It is particularly useful when repairing split or damaged door jambs, as it bridges and reinforces the affected area while restoring full strike functionality. The single-pack format is intended for single-door installations. It fastens directly into the jamb and door frame using the included screws.
