Like bench dogs, the Wonder Dog Clamps use 3/4" holes, which are common in so many benches, they are ideally suited to the Veritas bench dog and bench pup to securely hold straight, curved and irregular shaped objects thanks to the ability to position in a variety of holes, the long acme style thread and even the possibility of attaching specifically shaped clamping tips to the brass clamp head using the two pre-drillled holes. The brass head is 15.9mm high, allowing the swivel handle to enough rotation to be used at its lowest projection.
The wonder pup uses an O-ring rather than the side spring the wonder dog uses. Made in Canada.
