    Note: The FabBlock and mini-block have sides with our standard hole pattern, and can be expanded by either using our fabwings or by bolting multiple blocks together. The options for sizes and configurations are essentially endless with the Mini-Block and FabBlock style tables!


    • The pro tables use one of the heavy duty leg kits.
    • Mini-Blocks, FabBlocks, and plasma tables use our FabRack.
    • The FabRacks can be purchased with or without casters!


    • We do not offer the pro table in thicker material. Due to the rib structure design, they are limited in size (largest 3x4) and thickness.


    • Threaded holes are very convenient for bolting your fixtures or our accessories to the table. Threaded holes are the quickest way to set things up on the table.
    • When you order threaded holes, the sides of the table will have the threaded pattern as well.
    • Pro tables are not available with threaded holes as there is not enough material. To attach accessories to the pro tables you would want to use parts FBN-2 and FBS-2, the fabnut and fabnut locating spacer washer.


    • We do have a 4-pack of squares available at a discount, parts VFS-2 and VFS-4. All other accessories are a la carte.


    • Fabnuts are threaded and have an o-ring. They insert into the 16MM hole from the underside of the table and are held in place by the o-ring.
    • The fabspacer fits in the 16MM holes on our accessories and allow you to get accurate placement with a 3/8-16 bolt.


    • We do offer in house assembly by our pro welders. The cost depends on the size of table or accessory.
    • For rates contact admin@tabandslot.com


    • It depends on our workload, currently about 10-14 business days to ship.

      Excellent quality

      This is my first fab table I have bought. Was super simple to put together. Everything lined up perfectly. Highly recommend this table to anyone that doesn’t have space for a larger table.

      2’x4’ fabRack.

      This is so easy to put together and looks great. The only complaint I have is that the provided hardware to attach the legs to the top are about a 1/4” shorter than needed (when used with my 1/2” thick top). After all, there is no point in having locking nuts if the bolts are too short to reach the locking portion. As you will see in the photo, they do not work as intended. Otherwise this would definitely have been a 5 star review.
