Security Plates, Surface Bolts & Peepholes | OEM Replacement Parts

OEM Security Hardware for Retrofit and New Construction

Security plates reinforce frame and door edge vulnerabilities. Surface bolts provide manual locking on interior faces; chain bolts limit opening distance. Latch shields cover cylinder holes and strike areas. Door viewers enable resident identification before entry. Each component addresses specific weak points in door assembly security. Proper sizing and installation ensure code compliance and durability under repeated use.

Compatibility Across Door Types and Frame Styles

Replace worn or missing security hardware on hinged doors, storm doors, and screen doors. Identify your frame material (wood, aluminum, steel), door thickness, and existing mounting pattern. Security plates install over existing hardware; surface bolts mount to door interior face; peepholes require pre-drilled holes or new drilling. Cross-reference OEM specs to confirm finish (brass, stainless, chrome) and backplate dimensions.

Specification Selection: Backplate Size, Bolt Length, Viewing Angle

Surface bolt depth must match door frame depth; chain bolts limit opening to 4–6 inches typically. Latch shields cover 1–2 inch cylinder holes; wrap-around plates extend 6–10 inches vertically. Peephole lenses range 160–200 degrees; select based on door thickness (1.375–1.75 inches standard). Confirm strike plate alignment before ordering; misalignment defeats security purpose.
