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.
Installation of the PW20 Right Angle Picture Frame Spring Clip
Place the frame face-down on a padded mat. Load the content stack (glass, mat, artwork, backing board) into the rabbet. Hold the S02 clip with the 90° foot aligned squarely with the inner rabbet shoulder. Press down firmly until the foot snaps under the rabbet lip and the clip body lies flat on the backing board surface. The spring tension locks the stack in place immediately.
When to Choose S02 Over S01
Choose the PW20 Right Angle Picture Frame Spring Clip when: your moulding has a machined 90° rabbet shoulder; you are building frames for permanent archival display where any movement must be minimised; or you are producing frames professionally and require the most positive clip engagement available in the small-clip category.
Mixing S01 and S02 in the Same Frame
Some framers use S02 clips at the corners (where the rabbet shoulder is most precisely square) and S01 clips along the straight sides (where slight irregularities from hand cutting may benefit from the angled foot’s self-adjusting action). This hybrid approach combines the best of both variants.
Comparing PW20 Right Angle vs. Other XKY Framing Spring Clips
The S02 shares the same application range as the S01 — small frames in the 4×6 to 8×10 inch range — but with superior seating stability on precision rabbet profiles. For larger frames requiring more spring travel, the PW22 medium clip (S10) at 47 mm or the PW16 large clip (S11) at 52 mm would be appropriate upgrades.
