The PW17-2 Medium Width Picture Frame Spring Clip (SKU S07) is the medium-format specialist in XKY Framing’s serrated-foot spring clip family. With a 24 mm wide body and the grip-enhancing serrated foot of its larger sibling the PW17, the S07 provides superior lateral stability for medium-sized frames — 25×35 cm to 40×50 cm — where standard small clips may lack sufficient coverage and the full-size PW17 is unnecessarily large.
Serrated Foot Technology in the PW17-2 Medium Width Picture Frame Spring Clip
The defining feature shared by both the PW17 (S06) and the PW17-2 Medium Width Picture Frame Spring Clip (S07) is the serrated foot. The series of small teeth along the foot edges grip the inner rabbet surface mechanically, preventing the clip from sliding laterally under the weight of the glass panel or during frame transport. This mechanical grip is particularly important in medium frames — large enough that the glass panel weight is significant, but often assembled and transported repeatedly in a workshop environment where undetected clip migration can lead to loose content in the finished frame.
Optimised for Medium-Format Frames
At 24 mm wide and 17 mm tall, the S07 strikes the balance between coverage and compactness that medium frames require. The 10 mm tall head slot accommodates rabbet lips from the thinner profiles common in medium wood mouldings. The 4 mm body slot depth is appropriate for standard single-mat or light double-mat configurations — the primary content assemblies in medium-format display frames.
At 0.8 g, the PW17-2 is lighter than the PW17 (1.7 g) but still heavier than PW20 (0.5 g), reflecting its intermediate size and holding capacity position in the XKY range.

Installation Guide
With the medium frame face-down on a padded surface, load the content stack. Position the PW17-2 clip with the serrated foot over the rabbet edge. Press down until the foot snaps under the rabbet lip — the teeth will grip immediately. Space clips every 6–8 cm along each side, or use 3–4 per long side and 2–3 per short side for a standard 30×40 cm frame.
When to Choose PW17-2 Over PW20
Choose the PW17-2 Medium Width Picture Frame Spring Clip over PW20 clips when: your frame is 25×35 cm or larger; your content stack includes a heavy glass panel; your frame will be transported frequently; or your moulding’s rabbet width is 20 mm or more, making the wider PW17-2 body a better fit than the narrow PW20.
When to Choose PW17-2 Over PW17
Choose PW17-2 over the full-size PW17 when your frame is in the 25×35 cm to 40×50 cm range, where the PW17’s 27 mm width may be unnecessarily large for the available rabbet width. The PW17-2’s 24 mm width fits a greater range of medium moulding rabbet widths.
PW17-2 in the XKY Framing Spring Clip Range
The S07 fills the medium-format niche between the PW20 small clip (S01, 7 mm wide) and the PW17 heavy-duty clip (S06, 27 mm wide). For large frames above 40×50 cm, the PW17 (S06) or PW16 (S11) is the correct choice. For small frames under 25×30 cm, the PW20 series (S01, S02) is more appropriate.
