This matte black strike is constructed from durable stamped steel and is designed for use with deadbolt and deadlatch locks on hinged doors. Its finish resists corrosion, making it suitable for exterior applications where weather exposure is a factor. The plate aligns with standard 5-1/2″ center-hole dimensions and is quick to install with existing mounting hardware.
Best for: Budget-conscious buyers who want a reliable, low-profile reinforcement option compatible with common deadbolts and latches. Its matte black finish also helps it blend with many door styles.
Limitation: This is a strike plate reinforcement element and may not address jamb damage or door alignment issues beyond the strike area.

This matte black plate reinforces both doors and knobs, suitable for 1-3/4″ thick doors with a 2-3/8″ backset. Made from hard stainless steel, it helps repair damaged doors and improves overall security against forced entry.

Best for: Buyers needing a robust, corrosion-resistant option that can be installed quickly on a variety of door types without requiring frame modification. The non-recessed design makes it a versatile fit for many situations.
Limitation: The plate is sized for certain door thicknesses; double-check thickness and bore compatibility before purchasing.
Reinforced Door Screw Kit — 3″ Screws
This kit includes 3-inch hardened screws and a square non-slip screwdriver bit, designed to fix strike plates, deadbolt plates, and hinges. The hardware is sized to burrow deep into the jamb, increasing kick resistance and overall door integrity. It is a cost-effective upgrade that complements a reinforcement plate for multiple doors in the home.
Best for: Do-it-yourself homeowners seeking to maximize security by upgrading fasteners, especially when installing larger reinforcement plates that require longer screws for proper anchoring.
Caution: Ensure compatibility with existing strike and hinge configurations to avoid misalignment or over-tightening.
HELEMAN Front Door Strike Plate — Dual Plate
HELEMAN’s dual strike plate features slightly taller latch and bolt openings with two strike holes for locks with 5-1/2″ to 6″ hole centers. This one-piece design reinforces the door jamb and increases screw count for added strength. It’s built from nickel steel and includes nine pre-drilled screw holes with six extra-long 3″ screws.
Best for: Homeowners dealing with taller latch/bolt configurations or doors that have experienced repeated strike plate loosening. The dual plate design adds redundancy and security against forced entry.
Limitation: Slightly larger plate may require a larger gap around the strike area; verify door geometry before installation.
Ferraycle 1 Piece Door Reinforcer Plate — Bronze Finish
This deep bronze reinforcement plate measures about 2-1/8″ aperture, 2-3/8″ backset, 5-1/2″ hole spacing, and overall 3-7/8″ width by 10-7/8″ length, suited for 1-3/4″ doors. Made of stainless steel with a bronze finish, it reinforces the latch area and door jambs to deter forced entry. It’s designed to survive wear and weather exposure while blending with darker hardware.
Best for: Buyers preferring a bronze-toned finish and a robust reinforcement solution for front-entry doors that may show wear around the strike area.
Limitation: Color variation may occur due to lighting and display differences; verify finish in person if possible.
Buying Guide: Key Considerations For Front Door Reinforcement Plates
- Door thickness and bore size: Most plates fit standard 1-3/4″ doors with 2-1/8″ bores. Confirm backset and hole spacing before choosing.
- Material and finish: Stainless steel options resist corrosion; consider color finish (stainless, matte black, bronze) to match existing hardware.
- Plate size and coverage: Larger, oversized strike plates can cover damaged jamb areas and improve alignment; smaller plates are easier to install on tight frames.
- Installation hardware: Look for included screws and Torx bits for anti-tamper security; ensure the kit covers strike, hinge, and deadbolt components if upgrading multiple points.
- One-piece vs dual-plate designs: One-piece strike plates are simple; dual-plate designs offer extra coverage and kick resistance in vulnerable doors.
- Security goals: If the goal is to prevent forced entry, prioritize reinforced strike areas and longer screws that reach deep into the jamb.
- Maintenance: Choose corrosion-resistant materials for exterior doors and consider weather exposure when selecting finishes.
