S01-PW20 Small Picture Frame Spring Clip

The PW20 Small Picture Frame Spring Clip (SKU S01) is XKY Framing’s most compact and lightweight stainless steel frame-securing clip, engineered for picture frames in the small-to-medium size range. Stamped from 0.5 mm thick stainless steel sheet, it delivers reliable spring tension that holds glass, mat board and backing board firmly in the frame rabbet — without screws, nails or any additional fasteners.

Why the PW20 Small Picture Frame Spring Clip Is the Industry Standard for Small Frames

The PW20 Small Picture Frame Spring Clip has earned its place as the default choice for small frame assembly because of its perfect balance of compact dimensions and effective clamping force. At 33 mm in total length, it fits comfortably inside the rabbets of small picture frames with profiles as narrow as 12 mm. The 7 mm body width keeps the clip well within the inner rabbet channel, while the 6 mm clip head grips the frame content stack — glass, mat and backing — with consistent spring pressure.

The stainless steel construction ensures the PW20 Small Picture Frame Spring Clip resists corrosion in both indoor and temperature-variable environments, important for frames displayed in kitchens, bathrooms or coastal homes where humidity fluctuates. The bright silver finish blends inconspicuously with the natural colour of frame backs, maintaining a professional appearance on the finished piece.

Precision Dimensions for Perfect Fit

Every dimension of the S01 has been engineered with frame-making precision. The 4 mm × 4 mm slot accepts the inner lip of standard wood moulding rabbets without excessive play. The angled foot (11 mm wide, 9 mm tall) provides the spring geometry that generates holding force proportional to the content stack thickness — thicker stacks compress the spring further, increasing grip automatically. The 3.5 mm angled tip facilitates easy insertion under the rabbet lip without scratching the frame’s inner channel.

At just 0.5 g per clip, the S01 adds negligible weight to the overall frame assembly. This matters for hanging hardware calculations on lightweight frames displayed on standard picture hooks.

Installation Guide for the PW20 Small Picture Frame Spring Clip

Installation requires no tools. With the frame face-down on a padded surface, load the glass, mat (if used) and backing board into the rabbet. Slide the clip foot under the rabbet lip at a shallow angle, then press the clip body down flat against the backing board surface. The spring tension will lock the assembly in place. Repeat at regular intervals around all four sides — typically 4–6 clips per small frame.

Recommended Clip Spacing

For frames up to 20 cm on the shortest side, place clips every 6–8 cm. For frames 20–30 cm on the shortest side, use the medium PW22 clip (S10) or reduce spacing to every 5 cm. Consistent spacing prevents bowing of the backing board, which can cause moisture damage to prints over time.

Tips for Difficult Rabbets

If the rabbet is very shallow (less than 8 mm), the clip foot may not seat fully. In this case, the PW13-2 clip (S05) with its lower 8 mm profile height may be a better fit. Always test one clip before installing the full set.

Applications for the PW20 Small Picture Frame Spring Clip

The S01 is widely used by professional framers, DIY frame makers, and frame manufacturers for: standard photo frames in 4×6, 5×7 and 8×10 inch sizes; art print frames in A5 and A4 sizes; certificate frames; small canvas float frames; and mirror frames with thin moulding profiles. Its compact size makes it the only practical choice for narrow-profile mouldings where larger clips would protrude beyond the frame back.

PW20 Small Picture Frame Spring Clip vs. Larger Spring Clips

Compared to the PW22 medium clip (S10, 47 mm) and PW16 large clip (S11, 52 mm), the S01 PW20 is optimised for smaller frames where the shorter spring body still generates sufficient holding force. For frames larger than approximately 30×40 cm, consider stepping up to the PW22 or PW16 for greater spring travel and holding force.
