Each Micro Jig ZeroPlay Guide Bar is composed of two interlocking plastic bars that adjust laterally to the exact width of your miter slot to stabilize your jigs. Guide bars are easily calibrated from the top of jigs and fixtures and are easy to retrofit. The ZeroPlay Guide Bar is a "One-Touch Calibration" miter bar (9-1/2" in length) that has two stacked half bars with opposing wedges that expand parallel evenly to fit the exact width of a standard miter slot for a perfect fit and smooth glide, even fits tricky Shopsmith™ or General's miter slots.

Easiest Miter Bar Install
After fighting the aluminum miter bars to get an exact fit, this miter bar was super simple to install on a sled for a Sawstop Contractor saw. You'll want a 1/2" flat bottom drill bit to make life easier. Had full adjustment capabilities after install onto sled which was awesome. Highly recommend!

Review of Micro jig
I have a Shopsmith which has a slightly narrower miter slot than other table saws. Therefore, most commercial miter bars will not fit. The micro Jig fits perfectly. I use one on a number of jigs I have created to enhance safety in my wood working.

Works as Advertised!
Easy to install and very stable! With a table saw sled, perfect 90-degreee cuts are easily repeated, with no exception. Even with temperature fluctuations, there is no need to adjust.

I saw this on a "Tommy Mac"video, but installation and alignment were somewhat easier than he demonstrated.

Great Product
Great easy install, recommend a pair instead of one zero play bar when building larger size jigs. You do not really need the zero play stop as you can easily make your own.

Great for making tablesaw sleds
I have tried making guides out of wood and plastic with limited success. Also I have used three guides made of metal and this product beats them all. Not only is it easy to install, it is light weight and should not wear down over time like the other materials. It works great as a single runner on every one of my sleds.

Want to make my own sled and the reviews on this looked great
jkucharik on Feb 15, 2018
would rather have had the 18" miter bar but the reviews on those were poor. Have used these in the past and they are not great but ok.

I'm hoping to be able to grind it down a bit to fit in my band Saw's non-standard miter slot.

video shows how easy it is to get exact miter slot tracking without worry of distortion due to change in humidity.
Evie W on Nov 11, 2016
Easy to adjust to fit groove. Slides easily and does not change with humidity.
Stuart S on Oct 28, 2016
This is the "Cadillac" of guide bars for your table saw jigs. You can always cut your own, but this one allows you to dial it in for a snug and smooth fit that's hard to master with wood only.
2Dog Projects on Jan 6, 2016
Have made jigs with two others and find them very accurate.
Stuart on Nov 25, 2015
Was having problems building my own sled. The sleds I have built keep coming out loose and messing up my cuts. I saw these on several woodworking YouTube videos. Hopefully they work.

I bought the zero play and it doesn't fit in my tablesaw tracks. Do they make a smaller size?
Jason C on Oct 28, 2016
BEST ANSWER: If your tablesaw has standard 3/4 x 3/8 inch tracks the ZeroPlay guide bar will most certainly fit in them. On the instruction sheet follow assembly steps 1 through 5 which coordinate with illustrations A, B and C. If you don't have the ZeroPlay Stop referred to in step 2, clamp a piece of scrap wood of the proper dimensions into your track that will serve the same function as the ZeroPlay Stop.
What is smallest adjustment on micro jig zero clearance?
kevin R on Sep 22, 2019
BEST ANSWER: Zero, inches or mm, take your pick.

But seriously, there are no 'increments' you put the 2 parts together, in the loosest position, insert it into the slot, move the top piece to touch the sides of the slot, then apply 2 hairs and some air in pressure and tighten the lock screws.. if you use 3 hairs worth of pressure it'll be too tight and won't slide smoothly, so don't over do the pressure.

It's truly a some design that adjust exactly to the slots.
Will this work on my DeWalt dw745?
Richard M on Dec 14, 2017
BEST ANSWER: The slide will fit any saw with the standard 3/4" track. Measure width and depth of track to determine if it is 3/4 x 3/8. The slide will adjust to make a tight fit with little to no movement side to side.
I saw where one reviewer said that one bar was enough for a table saw sled. Has anyone else found that to be true?
JOE Z on Apr 7, 2016
BEST ANSWER: There is a little play in your sled if you use only one. For a cross cut sled, I would use 2.
Description says this sold as a set. What is meant by set? Is it 2 bars?
Jerry on Aug 29, 2018
BEST ANSWER: The set includes two interlocking plastic bars and the associated assembly hardware.
I have two craftsman table saws mod # 137.218020 and 137.218072. They both have tabs on the top, and both are just a tad ov er 3/4 inch wide and are 3/8 inch dxeep. Will this jig fit my saw's?
gunslinger on Dec 28, 2017
BEST ANSWER: I have a DeWalt table saw with a similar set up as your Craftsman. The Rockler jig fit and could be adjusted for zero play without any problem.
