Perfect Fit Door Strike Shims (2mm, 3mm, 4mm) Set

These door strike shims come in a set of three thicknesses (2mm, 3mm, 4mm) to fine-tune latch alignment for interior and exterior doors. The shims are manufactured via a 3D-printing process using PETG plastic for durability and a compression-resistant profile. Aesthetics are considered with color options in black, white, or gray to blend with most door frames. Each set includes multiple shims to accommodate different strike plate openings. Note that longer screws are not included, so verify existing screw lengths prior to installation. The maker team offers personal support for sizing and fit questions.
Reference features include a compact size for precise adjustment and a straightforward installation path behind the strike plate. The shims help raise or align the latch to reduce sticking doors, improve closure, and enhance overall door security by ensuring the latch engages securely. This option is particularly useful for doors with minor gaps or slight misalignment from frame settling.
MOSECYOU Door Strike Shim Plates, 3 Thicknesses

This MOSECYOU set provides three different thickness options to raise the striker plate and bring the latch closer for doors that don’t stay shut. Made from hardened stainless steel, the all-metal construction offers strong support and durability. It fits standard strike plates and is designed for quick installation behind the strike plate, with screw holes spaced at 1-5/8” for compatibility. The kit is available in black or silver finishes, depending on the model, and aims to prevent latch bypass caused by wood shrinkage or oversized gaps.
The product line emphasizes security by reducing the chance of prying or card entry while restoring reliable closure. Because it is a metal shim system, it is less susceptible to wear over time compared with plastic alternatives. This makes it a solid choice for doors that experience seasonal swelling or frame settling. Be sure to match the strike plate dimensions and screw hole spacing to your door setup.
MOSECYOU Standard Door Strike Spacer Shim Plates

These shim plates come in a set of three distinct thicknesses, intended for standard strike plates. The kit uses hardened stainless steel to provide improved stability and longevity. Installation involves placing the shim behind the strike plate to adjust the latch distance and close gaps caused by seasonal wood movement. The design supports quick, non-invasive fixes without cutting into the jamb. The product notes emphasize compatibility with standard strike mechanisms and the need for correct screw-length verification before mounting.
The MOSECYOU approach emphasizes durability and a clean finish, available in black or silver. It is suitable for homeowners seeking a robust metal solution that aligns with standard hardware. Prospective buyers should consider whether their door gap is primarily horizontal or vertical to determine the best shim thickness combination for achieving reliable latch engagement.
MOSECYOU Door Lock Strike Plate With Shim

This MOSECYOU kit pairs a standard door strike plate with a stainless steel shim to fix doors that won’t latch properly due to frame or door shrinkage. It includes an integrated shim plate and three wooden dowels to fill old screw holes if needed, enabling a cleaner installation. The kit is designed to replace a worn strike while keeping a secure latch engagement. It is compatible with standard strike openings and screw hole spacing of 1-5/8 inches. The dowels help mitigate stripping or loosening from prior hardware.
Material quality and installation simplicity are central to this option. The thick metal construction supports long-term resilience, and the included applicator bits and dowels assist in achieving a solid, non-slip latch. This solution is practical for doors that experience seasonal expansion or shrinkage that affects latch alignment, particularly on exterior doors where secure closure is essential.
Perfect Fit Door Strike Shims (Black) Set

This black variant of the Perfect Fit door strike shims mirrors the 2mm/3mm/4mm set described earlier, offering a cohesive aesthetic with black hardware. The combination of PETG material and a three-thickness set enables precise alignment to address door closing issues stemming from frame wear or misalignment. The same installation caveats apply: verify screw lengths, as longer fasteners are not included. The included thicknesses ensure flexibility for minor to moderate misalignment scenarios. The manufacturer offers direct support for sizing and installation queries.
In practice, these shims can provide a quick, non-destructive remedy for doors that won’t latch consistently. For doors prone to sticking or misalignment due to seasonal changes, this set provides multiple options in a compact package. The choice of color also allows the shim to blend with existing hardware, reducing visible hardware mismatches while improving latch reliability.
Buying Guide: Key Considerations For Door Latch Shim Purchases
- Material and durability: Stainless steel and PETG offer different benefits. Metal shims are generally more durable for external doors or high-traffic areas, while PETG options can suffice for interior doors with lighter usage.
- Thickness options: A set with multiple thicknesses (e.g., 2mm, 3mm, 4mm) enables precise adjustment for various frame gaps and latch positions. Assess your door’s hinge alignment and latch strike distance to pick appropriate combos.
- Compatibility: Ensure the shim set matches standard strike plate dimensions and screw hole spacing (commonly 1-5/8”). Some kits include dowels or fillers to address old screw holes or oversized holes.
- Installation impact: Look for kits designed to install behind the strike plate with minimal jamb modification. This preserves door aesthetics and avoids lengthy carpentry work.
- Security considerations: While shims help closures, verify that the chosen solution does not undermine strike plate integrity or door security, especially on exterior doors.
- Support and documentation: Some sellers provide personal guidance or installation tips, which can be valuable if you’re unfamiliar with strike-plate adjustments.
- Finish and appearance: Color-matched options (black, white, gray, or silver) help the shim blend with your hardware for a cohesive look.
