I just received my (Black Friday splurge) Jet parallel clamps today, and was a bit disappointed in the release lever. Even after pulling up on the level, it’s rather hard to move the clamp head. Out of the 4 I purchased, only 1 of them slides nice and smoothly.

I wanted to know if this is normal for the Jet parallel clamps, and if the operation becomes smoother after some use?

Mine are the same. I have to slightly “tilt” (by lifting/pushing on the screw handle- I forget which) the sliding head to get them to move freely.

Lew – Yep definitely user error. I was fin-nicking around with them just after posting this forum topic, and tried lifting/pushing like what I’ve come to do when playing with the Besseys and Jorgies, and it now works like a charm.

All – I thought I’d add a few additional questions now that I have a chance to play around with the clamps a bit more. I noticed that the two 40” clamps still seem to get stuck at various lengths of the bar. On closer inspection, it appeared that there the bars have some dings on them, for example equally spaced at the ruler markers (on the 7, 8, and 9” marks).

While it doesn’t render the clamp inoperable, it does interfere with the clamp head movement, causing a sudden thud and stop when sliding the bar forward or back. I am talking to Jet customer service about this but I am wondering if anyone else has noticed imperfections (such as these) on parallel clamp bars being an issue?

All – Just a quick update. After conversing with Walter Meier customer service, I was sent 2 replacement clamps for the 40” clamps that get stuck randomly. The new clamps don’t have the same release lever + binding problem of the original 2 in the set and slide VERY smoothly. Kudos to Walter Meier for the hassle free customer service.

I made a note of this in another thread, but this is specifically the issue I’m having with my Jet clamps, too. All 4 of my clamps are very difficult to slide, and when I removed the head to reverse it (for spreading), it wouldn’t even go back on the bar.

I’m pretty sure it’s the spring that’s interfering with the sliding. I took my clamp apart and the spring (has a rectangular cross section that the bar passes through) doesn’t really locate on the locking lever, so it gets hung up easily on the bar’s ridges. I would bet if the steel locking tab had ridges that located the spring away from the bar the slide action would be way better.

I considered taking my clamps apart to inspect what the issue was, but I never got very far. I think I took off the face plate, found something more complicated than I liked, and gave up.

I have about half that slide easily and half that slide kind of rough. I hope after some use they’ll free up.

After the initial issue with the release lever and positive customer service experience (they let me keep the “defective” clamps), I can say that my clamps have exceeded my expectations and serve me well.
