Works very well and easy once you figure it out!

Use a framing square . . . ALWAYS . . . But, it is a great straight edge clamp that will stay where you put it!

I will most likely buy the long one too when I decided which width I want.

This tool works well, but it requires a framing square to line it up. Their accessory wide jaws don't really help to make it line up square either. And if it ain't square, you are wasting material. Use a framing square . . . ALWAYS . . . But, it is a great straight edge clamp that will stay where you put it!

This thick aluminum guide clamps securely, is rigid and very straight.

It compares nicely with my Starrett straight edge which is certified to within + / - .002" per foot. I used feeler-gauges to interrogate its straightness side-to-side with the Starrett straight-edge, and found small gaps along the length, but no more than a couple of thousandths. That is as good as most of us ever need to guide a saw or draw lines.

The clamping mechanism works well and has held up for the four years I've used it. My only complaint about the system is that the other end, where you set the rough distance, was a little sticky and rough at first. After using it a bunch and waxing the undercarriage, it now works much more smoothly.

The hole on the clamping end allows you to hang this safely away from other tools that might bang it out of kilter. That's a small feature, but appreciated.

The clamp has different positions for different clamping force. The center position does not clamp as hard. That's good when cutting thin sheet goods, since too much force bends the sheet.

Pressing the blue-lever fully down increases clamping force, which is better for thicker sheets or solid wood.

Those features are great and despite rough-frequent use, these are still working well. (I have three) But that's not why I love them so much... You can use this to make your own track saw at a fraction of the price of expensive teutonic tools!

First, I put a square-edge on one end of the guide to help square the straight-edge to the work quickly. You can skip this step and just use a framing square. I did that for the first year I used it.

Then, I modified my cheapest circular-saw's base by adding a 1/4" thick sheet of lexan.

I have always wanted a good straight edge for guiding a router or circular saw and this is a good one. You can find many uses for this clamp such as a fence for a drill press or band saw and in addition to being self locking, if you use it as a simple glue clamp, it has more than 600 psi. of clamping force.

The clamp itself is great on holding power. There are three positions with the locking handle. The aluminum is straight and without a bow and excellently packaged. The numbers and grid lines are clear and easy to read if need be and I think an all around good clamp device for the money. The non-metallic parts seem to be well manufactured with good materials and the entire clamp waranted for life as they indicate they will replace or fix it if anything goes wrong with the usual caveat that the waranty does not cover misuse or abuse.

There are also accessories available at extra cost such as a contractor saw plate, router plate and a wide jaw accessory as well as additional items for contractor use.

For the money, in my opinion, you can't go wrong with this item.

I was a little skeptical buying this clamp over the more popular store box model but with the measuring marks built into the straight edge I thought it was a better value. I have used it now for a couple of weeks and I am very happy with the product. I bought the 50 inch model to clamp across 7/16 OSB. It has yet to slip on me while cutting.

This is an amzing tool for use with a circular saw when you don't have a table saw large enough to cut a sheet of plywood. Very easy to use and extremely durable and accurate.

I have these in various lengths and they make quick work of cutting up sheet material. Like most other people I used a long straight edge for a while but these are waaaaay easier than clamps and a straight edge. They vary in width according to length to minimize deflection. They aren't cheap, especially the 99", but worth every penny.

I had a red clamp... you know, the "other" clamp line.
It unfortunately disappeared out of the back of my truck one day while parked at a #$@?%$#)&! (Big Orange) home improvement store. And yes, i have a cap on it which i stupidly did not lock.
I decided to give this Emerson a try since it was $20 less than the other one ($30 vs $50).
I like this even better as it seems to operate smoother and the clamping action works easier. At least for me.
But maybe it just seems better because i love that i was able to replace a tool at almost half the price of the original and with no drop off in quality or operation.

I purchased an all in one clamp and it shifts side to side and I can not get it to clamp on 4'x8' plywood. On plywood panel I push the sliding jaw tight then walk around to the other side of the work piece where the lever is. When I push down on the lever it doesn't clamp. There is about a 1/8" of and inch gap. I try to push the sliding jaw tight but when I clamp the sliding jaw does not stay in place.

The clamp seems to work better on smaller pieces which is awkward when you have so much of the straight edge sticking out. When I try to use it as a circular saw or router guide it shifts side to side on my mdf board.

So my issues are: 1. It does not clamp on plywood 48" in width because the sliding jaw moves when in the locked position causing

it to side shift.

2. When It does clamp on small pieces 20"-30" it side shifts.

I know it was locked in because when I attached it to the mdf board I tried to lift the clamp and it would not bulge. Using a digital protractor and a framing square I made sure it was square to the work piece. I then started my cut and about halfway through the clamp moved sideways, tilted up in the air, and fell off my Rockler Jaw Horse I had the board clamped in. As a result my wood piece was ruined by the router cutting a circular cut deeply into the wood. I used a 6' straight edge aluminum ruler and my Bessey clamps to make a guide and I finished my cuts perfectly.

I tried one more thing to see if I could get straight cuts with the all in one clamp. I needed to trim a 22" wide piece so I put it in my jaw horse with just enough space so that I could attach the all in one clamp square to the Jaw Horse's jaw's.
