Went into my local LV today. Saw the display for the Bessey Bar
Clamp sets. Then sitting on the table beside the clamps was a
display model for the Bessey 90 degree corner clamp. That's a beefy
heavy corner clamp.
$15 CDN I thought it was a good price and grabbed it.
Later I checked; LV does not sell this item online. Rockler and
Woodcraft have it advertised at $29 USD.
If you interested, and live near an LV and looking for a corner clamp,
it's worth driving over and taking a look.
