What exactly is this clamp guide for?

[Mark Gibney]

I got this clamp guide amongst a bunch of regular guides.
I don't know what it's designed to do, or how it should be used. Hopefully the pictures are clear - it is the same thing back to front.

The first two photos slid sideways, apologies.

thanks, Mark

Mark, I’ve seen them used as saw guides, like the one in the picture at this link. (https://www.harborfreight.com/50-inch-clamp-and-cut-edge-guide-66581.html?utm_source=google&utm_medium=cpc&utm_campaign=12169518939&campaignid=12169518939&utm_content=128369727995&adsetid=128369727995&product=66581&store=3371&gad_source=1) There may be other uses I’m not aware of.

I was also going to say a saw or router guide. But it seems like there are two guides attached together that are opposite each other which I don't understand. I can't think of a reason to have two different clamping set-ups opposite of each other like that.

Are you certain that is not two clamps that are stuck together with double sided tape or some sort adhesive.

It's called a back to back clamp. You can clamp it to the bench and then clamp boards on top.

Clamp one side to your work surface and clamp your workpiece in the other.

Richard, thanks for that info, I've never seen one of those before. It looks like Pro-Grip actually calls that a Twin Clamp, the Back to Back is slightly different. I can certainly see a use case for that style of clamp.

Good to know, thanks. Seems it might be of more use on a job site than in a shop.

Yea, saw guides. Somewhere I may have one of them still hanging around from when my (previous) shop was young. They work fine as long as you carefully position and clamp them, taking into account the necessary offset to have the blade on the line. (and on the correct side of the line. ;) ) Can be used with multiple tool types...saws, routers, etc.

Saw guides work well for cutting drywall.
Not as good as a t - but - good in a different way. (main reason being - I have one ;) )
