What this is
A bench-mounted clamp that installs into a 3/4" (20mm) bench dog hole via a cast-aluminum base, rather than a T-track slot like the POWERTEC 71168, Rockler Auto-Lock, and Milescraft 4007 already on the site. If your bench has dog holes but no T-track, this is the mounting-compatible option among the hold-down clamps covered here.

Kreg KBC3-BAS Automaxx Bench Clamp with Base
Mounts via bench dog hole rather than T-track — the compatible option if your workbench or Mobile Project Center has dog holes but no T-track slot.
View Price on AmazonWho this is for
Workbenches or project centers with standard 3/4" dog holes but no T-track — this gives you a swiveling, auto-adjusting hold-down without needing to add track to your bench.
Who this isn’t for
If your bench already has T-track, the Rockler Auto-Lock covers a wider auto-adjust thickness range (0"–2-3/4" vs this model’s up-to-3-1/2" fixed-format capacity) and doesn’t require dog holes specifically.
Bottom line
Manufacturer-sourced specs, not a hands-on test. On paper the standout feature is dog-hole mounting compatibility — a genuinely different attachment method than every other hold-down clamp on the site. Kreg KBC3-BAS if your bench has dog holes rather than T-track.
