The PW16 Large Picture Frame Spring Clip (SKU S11) is the flagship spring clip in XKY Framing’s flat-body range. With a 52 mm total length — the maximum in the PW family — and a wide 14–16 mm foot, it delivers the greatest spring travel, the most stable seating, and the highest holding force of any flat-body clip in the catalogue. It is the definitive choice for large frames, heavy glass panels, deep content stacks, and professional conservation framing in the 50–80 cm format range.
Maximum Spring Travel: The Core Advantage of the PW16 Large Picture Frame Spring Clip
Spring travel — the distance a clip can flex before engaging the rabbet lip — determines how thick a content stack the clip can accommodate. The PW16 Large Picture Frame Spring Clip’s 52 mm body provides the greatest spring travel in the XKY flat-body range, approximately 50% more than the PW22 (47 mm) and 57% more than the PW20 (33 mm). This maximum spring travel translates to two concrete advantages: accommodation of the thickest content stacks (up to approximately 18 mm), and maintenance of consistent spring force across the full stack depth range — from thin to thick — without the clip either bottoming out or losing tension.
For professional conservation framers who work with archival glass, spacers, museum-quality mat board, original artwork and foam board backing — content stacks that can easily reach 12–18 mm — the PW16’s generous spring travel is not a luxury but a necessity.

FAQ
What is the maximum content stack thickness the PW16 can accommodate?
The PW16's 52 mm spring body and 10 mm slot depth can accommodate content stacks from standard single-mat (approximately 6–8 mm total) up to approximately 15–18 mm for deep assemblies with 3 mm glass, double-mat, spacer and 5 mm foam board backing. For stacks beyond 18 mm, a right-angle clip such as PW18-3 (S09) is recommended.
Is PW16 the largest spring clip XKY Framing offers?
PW16 (S11) at 52 mm is the longest flat-body spring clip in the XKY range. For wide-body requirements (holding force across wide rabbets), the PW17 (S06) at 27 mm wide provides broader coverage per clip. For deep-rabbet right-angle mounting, PW18-3 (S09) is the largest option.
Can PW16 be used for mirror frames?
Yes. Mirror frames often have deeper rabbets to accommodate the mirror thickness, and the PW16's 52 mm spring body and 10 mm slot depth are well-suited to retaining mirrors in the 50–80 cm range. Ensure the mirror edge does not contact the stainless steel clip directly — use a soft-edge bumper between mirror and clip to prevent edge chipping.
Can this machine be customized?
Yes. S11 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.
