CompX Strike Plate, Black 1500/Pack, SP-257-3

SP-257 Strike Plate Black For Double Door Locks

SP-257 strike plate black is a CompX Timberline Lock strike designed for use with double door locks, so it gives you a defined locking point when you are securing paired cabinet doors. The Z shape configuration described in the product data provides an offset profile, which helps the lock bolt engage cleanly when doors are not on the same plane. The 1/4 DP detail in the description indicates a quarter-depth design, which keeps the strike low profile so it works in tight cabinet layouts. The black finish referenced in the name and description provides a dark, uniform appearance, which helps it blend with black or dark-toned lock bodies and cabinetry. Being part of the Locks and Latches category and the Strikes product class means it is purpose-built as the receiving point for a lock, which matters when you want repeatable door alignment and reliable lock engagement on double doors.

Key Strike Plate Details For Lock Projects

• The SP-257 strike plate is identified for use with double door locks, so it supports cabinet layouts where two doors meet and need a shared locking point, helping keep both doors secured off a single lock body.
• The Z shape noted in the SAP description creates a stepped profile, allowing the strike to meet the lock bolt even when the strike mounting surface sits slightly offset from the lock, which helps reduce binding during operation.
• The 1/4 DP detail identifies a quarter-depth style, so the strike adds minimal projection off the mounting surface, which is useful where interior clearances are tight behind cabinet doors or within lock housings.
• The black finish called out in the product name and description gives the strike a dark appearance, so it visually ties in with black CompX Timberline lock components and dark cabinetry, supporting a consistent hardware look.
• The SP-257-3 manufacturer part number and CompX Timberline Lock branding connect this strike directly to the Timberline lock system family, which helps match strikes to existing specifications on cabinet and fixture drawings.

Strike Plate Mounting And Screw Details

The web description specifies that SP-257 strike plates are sold without screws, and it calls out the use of #6 x 1/2 Panhead screws, so the mounting holes are sized to work with that screw pattern. Using the called-out #6 x 1/2 Panhead screws means the head seats properly over the strike flange, which helps hold the Z shape strike firmly against the mounting surface. Because the strike is described with a 1/4 DP design, its lower profile reduces leverage on the mounting screws under use, which supports consistent alignment of the strike to the lock bolt. Being listed as a strike plate for use with double door locks, its mounting orientation is intended to receive the lock tongue at the meeting edge of paired doors, which supports predictable lock engagement along that joint.

Using This Z Shape Strike Plate In The Field

Where This SP-257-3 Strike Plate Fits Best

The SP-257 strike plate black is specified for use with double door locks, so it fits best on cabinets or enclosures where two doors close toward each other and need to be secured by a central lock. Its Z shape, noted in the SAP description, creates a stepped edge that allows the strike to bridge the gap between the door edge and the frame or opposite door, which is useful when surfaces are offset. The 1/4 DP description signals a relatively shallow profile, so it works in installations where the strike must sit close to the door edge without creating large gaps or interference. Because it is branded as a CompX Timberline Lock strike, it aligns with Timberline lock bodies often used in woodworking, cabinetry, and similar fixtures, so it integrates into those lock layouts where a matching strike is specified. The black finish referenced in the name and description also suits dark-stained or painted casework, so the hardware stays visually subdued in finished installations.

Why SP-257 Strike Plate Details Support Consistency

The combination of a Z shape profile and quarter-depth style means the SP-257-3 strike plate positions the lock engagement surface at a controlled offset, which supports repeatable alignment between the lock bolt and the strike. Using the specified #6 x 1/2 Panhead screws ties directly to the hole sizing described in the web text, so the fastener head covers the strike slots properly and helps resist movement over time. Because the strike is part of the Strikes product class under Locks and Latches, it is built specifically to act as the fixed counterpart to a CompX Timberline lock bolt, which matters when you want the door to pull to the same stopping point each time. The black finish called out in the description reduces visual contrast around the lock area on dark cabinetry, which helps installations look cleaner when multiple locks and strikes are aligned across a bank of doors. With its SP-257-3 manufacturer part number tied directly to this configuration, using this specific strike across similar double door lock locations helps keep hardware uniform from one cabinet or fixture to the next.
