The PRIME LINE PRODUCTS N 7334 is a satin nickel ball catch designed for interior door applications where a standard knob latch bolt is not needed or wanted. Constructed from diecast and steel components, this drive-in ball catch features a barrel measuring 0.75 inches by 1.1875 inches, a steel ball, a spring, and a strike plate. The assembly provides a spring-loaded latching action that keeps doors closed without a visible latch mechanism. Once installed, the hardware remains fully concealed, making it a clean solution for finish carpentry and millwork applications. Licensed contractors and finish carpenters are the typical installers.
The N 7334 is suited for residential and light commercial interior door installations, particularly on pairs of swinging double doors fitted with dummy knob hardware. The concealed design makes it appropriate for French doors, cabinet doors, and interior passage doors where a clean, hardware-free appearance is the goal. Each package contains 6 units, making it practical for multi-door jobs or stocking service vehicles. The satin nickel finish coordinates with standard interior door hardware finishes commonly found in residential construction and renovation.
Designed as a drive-in style replacement or new-installation ball catch for swinging double doors and interior passage doors fitted with dummy knob hardware where a standard latch bolt is not used.
Installation is typically performed by a finish carpenter or general contractor using a drill and appropriately sized spade or Forstner bit to bore the barrel hole. Ensure the door is held steady and the bore is plumb before driving the catch into the door edge. Align the strike plate with the catch ball location on the door frame or opposing door before fastening. Follow local building codes for door hardware installation in commercial applications.
