The PW20 Right Angle Picture Frame Spring Clip (SKU S02) is the precision-engineered 90° variant of XKY Framing’s best-selling PW20 small clip range. While the standard S01 features a tapered angled foot, the S02 sports a perfectly square 90° foot that seats flush against square-profile rabbet shoulders, providing a more stable, rattle-free installation on precision-machined wood and MDF mouldings.
The Right Angle Advantage of the PW20 Right Angle Picture Frame Spring Clip
When a picture frame moulding is machined with a clean 90° rabbet shoulder — as is standard in high-end hardwood and precision MDF frame production — an angled-foot clip can rock slightly on the square corner, potentially creating minor movement over time. The PW20 Right Angle Picture Frame Spring Clip eliminates this by providing a 90° foot face that mates perfectly with the square rabbet edge, creating full face-to-face contact and a completely stable clip installation.
This flush seating also slightly increases the effective spring force transmitted to the backing board, since no energy is lost to clip rocking. Professional frame makers who work with precision-cut mouldings consistently choose the right-angle variant for its superior stability.
Dimensions and Material Specifications
The S02 measures 36 mm in total length — 3 mm longer than the standard S01 — to accommodate the square foot geometry while maintaining the same body spring length. The body width is 7 mm, clip head is 7 mm wide, the slot accepts standard 4 mm rabbet lips, and the tail end is 10 mm wide for a secure backing-board contact patch. Thickness is 0.5 mm stainless steel and weight is 0.5 g — identical to S01.
The stainless steel material ensures full corrosion resistance across all indoor display environments. The bright silver finish is consistent and clean, presenting a professional appearance on frame backs.

| Overview | <p>The PW20 Right Angle Picture Frame Spring Clip (S02) is the 90° foot variant of the popular PW20 series. Its square-cut foot seats flush against square-profile rabbet lips that are common in precisely machined wood and MDF mouldings, providing a more stable and rattle-free installation than an angled foot can achieve on right-angle profiles. Dimensions are nearly identical to the S01 but the foot geometry is 90° rather than tapered.</p> |

FAQ
What is the difference between S01 and S02 PW20 clips?
The S01 has an angled (tapered) foot tip optimised for rabbet lips with a slight chamfer or rounded inner edge, while the S02 has a 90° square foot that sits flush against a perfectly square rabbet shoulder. In practice, S02 provides a more stable, rattle-free seat on precision-cut rabbet profiles, while S01 is easier to insert on hand-routed or slightly irregular rabbets.
Does the right-angle foot make the S02 harder to install than S01?
The 90° foot requires the clip to be seated more precisely — it must be aligned squarely with the rabbet edge before pressing down. However, once seated, the square contact surface creates a more positive lock that many professional framers prefer for permanent installations.
Is S02 the correct clip for aluminium extrusion frames?
Some aluminium extrusion frames have a square inner channel that is compatible with the S02's 90° foot, but this depends on the specific extrusion profile. Measure the inner channel dimensions (compare to foot 11 mm × 9 mm) and verify there is enough depth for the spring body (36 mm length) to lie flat.
Can this machine be customized?
Yes. S02 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.
