MJ Splitter

Can I get replacement inserts for my MJ SPLITTER or MJ SPLITTER SteelPro without buying the whole kit?

MJ SPLITTER replacement inserts are only available from MICROJIG – they cannot be found in retailers. Shop Now

Will the MJ SPLITTER SteelPro fit in the original MJ SPLITTER holes I've drilled?

No, it won’t. The SteelPro needs its own separate drilling guide and its spacing is different than the original MJ SPLITTER.

I drilled my holes for the MJ SPLITTER askew on my ZCI. What do I do?
We’re really sorry to hear this. This will specifically happen for LEECRAFT brand inserts because they are very high-density. That’s why we recommend using wood or UHMW-based throatplates for the MJ SPLITTER SteelPro. To save your ZCI, you can fill the holes with epoxy and re-drill again using these instructions: Because the density of LEECRAFT inserts is much higher than most inserts. Thus, to install our splitter into a LEECRAFT insert; first, follow the instructions. Then after drilling lift the drill bit out a little bit and use either pressured air or a vacuum to get rid of some of the wood dust. Please note, do not take your drill completely out of the hole because a 90-degree angle for drilling is a requirement. Repeat this step until the hole is drilled through. This again is only for LEECRAFT brand inserts; because the inserts have higher density the hole will take very long to drill all the way through. Thus, the drill bit and wood dust will create a lot of heat energy melting your drill guide. If there’s an issue with your replacement drill bit and drill guide, we’ll send you a new one. If your ZCI is beyond repair, please provide proof or purchase of your LEECRAFT ZCI and we will reimburse you. Please call 1-855-RIP-SAFE (747-7233). BUY TODAY FIND A RETAILER


Will the ZEROPLAY work on my miter track?
The ZEROPLAY Miter Bar System works with both ‘T’ & ‘U’ shaped miter slots. The adjustable range is between 0.73″ – 0.785″ this means the width of the miter slot in which the Miter Bar will lay must be between these ranges. In detail, the very bottom part of a ‘T’ shaped miter slot must be within this specific range as well as a ‘U’ slot. Secondly, the thickness of the ZEROPLAY miter bar is 5/16″. Specifically, this means that the miter slot must be a minimum of 5/16” in depth. Moreover, considering a ‘T’ shape miter slot the area below the hinges must be 5/16″ or greater in depth, and considering a ‘U’ shaped miter slot the depth must be 5/16″ or greater. The ZEROPLAY Stop only works with ‘T’ shaped miter slots. All the same physical parameters apply to this product as the Miter Bar system; except of course only working on ‘T’ shaped miter slots.
