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.

FAQ
What is the difference between PW20 (S01) and PW22 (S10)?
PW22 is 47 mm long vs PW20's 33 mm — 42% longer — providing more spring travel and greater accommodation for thicker content stacks. The foot is also wider (13–15 mm vs 9–11 mm), giving a more stable seat on medium and large moulding rabbets. PW22 is designed for frames 25–50 cm, while PW20 is optimised for frames under 25 cm.
How many PW22 clips does a 40×50 cm frame need?
For a standard 40×50 cm frame, 4–6 PW22 clips on the long sides and 3–4 on the short sides provide excellent content retention. The 47 mm body covers more of the rabbet edge per clip than PW20, so slightly fewer are needed for the same holding force distribution.
Can PW22 be used on small frames as a substitute for PW20?
PW22 can physically fit in frames with rabbets long enough to accommodate its 47 mm body, but on small frames the longer body may extend beyond the rabbet edge, preventing proper clip seating. For frames under 20 cm, PW20 small clips (S01) are the correct choice.
Can this machine be customized?
Yes. S10 supports OEM customization including voltage (110V/220V/380V), pneumatic requirements, tooling, and export packaging. Share your moulding profile, daily output target, and destination market — our engineering team will confirm a factory-direct specification and lead time.
Do you provide overseas technical support?
Yes. XKY Framing provides remote commissioning guidance, spare parts supply, and video troubleshooting for hardware installations worldwide. For larger framing lines we can arrange on-site support by appointment. Contact us with your order reference for dedicated after-sales assistance.
