The PW22 Medium Picture Frame Spring Clip (SKU S10) is XKY Framing’s medium-format spring clip, providing the longer spring body and wider foot needed to retain content securely in frames from 25×35 cm to 50×60 cm. At 47 mm in total length — the longest clip in the flat-body PW spring clip family — it generates the greater spring travel that medium and large frames demand for reliable content retention across varied content stack depths.
Why Length Matters: The PW22 Medium Picture Frame Spring Clip’s 47 mm Advantage
Spring force in a frame clip is directly related to the length of the spring body: a longer spring body flexes over a greater arc, providing both more accommodation for content stack variation and more consistent spring force across that range. The PW22 Medium Picture Frame Spring Clip’s 47 mm body — 42% longer than the PW20’s 33 mm — flexes more before engaging the rabbet lip, accommodating content stacks from standard single-mat to thick double-mat configurations without the clip bottoming out or losing tension.
This longer spring travel also means the PW22 generates a more consistent holding force across different content assemblies in the same frame. A frame fitted with PW22 clips will retain its contents equally firmly whether it contains a thin canvas panel or a thick glass-mat-board assembly.
Wider Foot for Medium Mouldings
The S10’s foot is 13–15 mm wide — compared to 9–11 mm on the PW20 — providing a broader contact surface on medium moulding rabbets. This wider foot distributes the insertion force more broadly, reducing the risk of damaging the inner rabbet surface on softer wood mouldings. It also provides a more positive clip seating that resists rocking and lateral migration during content loading.

Installation of the PW22 Medium Picture Frame Spring Clip
With the frame face-down on a padded surface, load the content stack into the rabbet. Insert the PW22 clip at a slight angle — angled tip first under the rabbet lip — then press the body flat against the backing board. The spring will lock the content in place. For a 40×50 cm frame, use 4–6 clips per long side, 3–4 per short side, spaced evenly to distribute holding force.
PW22 for Art Print and Photography Frames
The PW22 Medium Picture Frame Spring Clip is especially popular with photography studios and art print framers who work predominantly in the 30×40 cm to 50×60 cm format range. Its length and spring travel are perfectly matched to the glass + mat + fine art print + foam board backing stack common in professional photography and limited-edition art print framing.
Storage and Handling
PW22 clips are supplied in bulk and can be stored in a small tray or container sorted by size. The bright silver stainless finish does not rust or corrode in typical framing workshop conditions. Avoid storing clips loose in a pocket with other metal hardware that could scratch the spring surface.
PW22 in the XKY Framing Spring Clip Range
The S10 bridges the gap between PW20 small (S01, 33 mm) and PW16 large (S11, 52 mm): PW20 for frames under 25 cm, PW22 for frames 25–50 cm, PW16 for frames above 50 cm. Stocking all three gives professional framers a clip for every frame size they encounter.
