What this is
A 90° corner-clamp square, the same basic category as the Bessey WS-3+2K and Irwin 226200 in our corner clamps comparison — it holds two boards at a right angle while you glue, nail, or screw the joint. The one feature that sets it apart on paper: the same clamp body is also marketed as a saw guide for 45° miter cuts, so it can help position a cut before assembly, not just hold the joint after.

Wolfcraft 3415405 Quick-Jaw Corner Clamp
Doubles as a 45° miter saw guide in addition to its corner-clamping function — a feature neither the Bessey WS-3+2K nor Irwin 226200 in our corner clamps comparison offers.
View Price on AmazonWho this is for
Cabinet and box-frame builders who want one tool that helps position a 45° miter cut and then holds the resulting 90° corner square for glue-up or fastening — the dual saw-guide function is the differentiator here.
Who this isn’t for
If you specifically need a manufacturer-published force rating to compare against other clamps, the Irwin 226200 (200 lb, in our corner clamps comparison) publishes one and this doesn’t. And if your joints are already cut and you just need to pull a gappy miter tight, the Rockler Miter Tight’s joint-gripping mechanism is a more direct fix than a corner-clamp square.
Bottom line
This is a retailer-cross-referenced spec writeup, not a hands-on squareness test. On paper, the standout feature is the dual-purpose saw-guide function alongside standard 90° corner clamping. Wolfcraft 3415405 Corner Clamp if that saw-guide function is useful for your workflow.
