NN22-90 Degree Positioning Block for 4-Sided Corner Nailer

90 Degree Positioning Block Corner Nailer – NN22 for 4-Sided Frames

The 90 degree positioning block corner nailer NN22 is a precision aluminum jig that ensures perfect right-angle corners on rectangular picture frames, mirror frames, and window profiles. Accurate corner alignment is critical to professional frame production—even a fraction of a degree error causes visible gaps and poor joint quality.

Why Use a Positioning Block on Your Corner Nailer?

A positioning block guides the frame corner into an exact angle position before the nail is driven. Without it, operators must manually align each corner, which is slow and inconsistent. The 90 degree positioning block corner nailer NN22 locks the miter-cut ends of your frame profile into a perfect V-channel, so every corner is identical and production speed increases significantly.

Specifications and Design

The NN22 features a precision-machined aluminum alloy V-shape with a 90° internal angle. The total span measures 213mm across both arms, with each arm extending 160mm and measuring 28mm in width. Two mounting holes—one per arm—allow secure bolting directly onto your corner nailer’s work table. The flat, machined surfaces provide a stable reference for repeatable corner positioning.

Applications

This 90 degree positioning block corner nailer jig is ideal for: rectangular picture frames, photo frames, canvas stretcher bars, aluminum window profiles, and any 4-sided frame construction requiring 90° corners. It is compatible with most standard pneumatic and CNC corner nailing machines.

Pairing With Other Angle Blocks

XKY Framing also offers the 120° positioning block (NN23) for hexagonal frames and the 135° positioning block (NN24) for octagonal frames, allowing your corner nailer to handle a wide variety of custom frame shapes with a simple block swap.

Installation

Mount the 90 degree positioning block corner nailer onto the machine table using the provided mounting holes. Align the V-channel with the nailer head position so the corner of the frame profile sits perfectly in the groove. Secure tightly and run a test piece to verify alignment before production.
