JET Universal Mobile Base, 18" x 18" to 28" x 28", 600 Lb. Capacity (JMB-UMB)

The JET JMB-UMB Universal Mobile Base has been a fantastic addition to my workshop, offering both mobility and versatility for my heavy machinery and equipment. This mobile base has made moving my tools around the workshop a breeze and has truly transformed my workspace. One of the standout features of this mobile base is its adjustability. It can be easily expanded from 18" x 18" to 28" x 28", making it compatible with a wide range of tools and equipment. Whether I need to move my table saw, planer, or bandsaw, this mobile base can handle them all with ease. The build quality of the JET JMB-UMB is exceptional. It feels sturdy and robust, capable of supporting heavy loads up to 600 pounds. The solid construction gives me peace of mind knowing that my valuable tools are secure and stable while in motion. Setting up the mobile base was straightforward. The assembly process was well-documented, and all the necessary hardware was included. Once installed, the base glides smoothly on its heavy-duty casters, allowing me to effortlessly maneuver my tools across various floor surfaces. The foot-operated levers for raising and lowering the base are a thoughtful addition. They provide quick and convenient height adjustments, allowing me to position my tools at the desired working height without any hassle. The locking mechanism holds the base firmly in place, ensuring safety during operation. Another notable advantage of the JET JMB-UMB is its compact design. When not in use, the base tucks neatly under my machinery, taking up minimal space in my workshop. This feature is particularly beneficial for smaller workspaces where maximizing floor space is essential. One small improvement I would suggest is adding rubber or non-skid padding to the base's contact points. Although the base is well-designed to protect floors from scratches, a little extra grip could enhance stability further. In conclusion, the base has been a game-changer in my workshop. Its adjustability, solid construction, and smooth mobility have simplified the process of moving heavy machinery. This mobile base is a must-have for any woodworker or DIY enthusiast looking to enhance the efficiency and organization of their workspace. I highly recommend it for its quality and value.

Very easy to use and heavy duty. Cabinet table saw rolls super easy now.

My son and I just purchased a Jet 8" helical jointer which weighs in at over 350lbs. We ordered the universal base on cost and flexibility. It arrived before the jointer in its on packaging which was in good condition. putting it together was a breeze with the different prefabricated slots. Assembly works best with two people although one person can get it done, it's just a little finicky. There are four corners which have to be assembled by sliding the end of one corning into the open slot on the adjoining corner. Easy peasy until you add the last corner as it will bind if it is not in exact alignment with the opposing side. This was a little frustrating at first because the pieces fit so well together, you just have to work at it. Additionally, two of the casters are fixed and the other two swivel so make sure you have them aligned to match how you intend to move the equipment it will be supporting. All casters will lock and once done, the jointer is pretty much immovable. For heavy equipment or other similar things, I recommend this mobile base. It allows us to move the jointer around our workshop with ease.

I love these mobile bases! I have three of them - one for my belt/disc sander; one for my router table; one for my scroll saw. As I have acquired each of these machines, I've researched all the other mobile bases I could find, but none (in my opinion) measures up to the Jet mobile base, at least for my needs. It's super easy to put together (no tools required); easy to adjust; maintains the power tool's position level and low to the floor; has two locking casters (locks are easy to activate and de-activate) and two swivel casters; and is relatively reasonably priced. Operation of the above machines does not put a lot of lateral force on the caster locks, though. I seem to have read one or more reviews where folks thought the locks didn't hold well enough when their particular machine was under use. Maybe that would be the case with a table saw or jointer, but I have had absolutely no problems with the holding power of the locks.

This took literally 10 minutes to assemble and another 10 to get my fully assembled Jet contractor tablesaw on it. The snap-lock springloaded pins made it very easy to adjust to width by holding it next to the legs of my saw and just sliding the pieces together. I did this solo, which was a little more difficult since the saw was pretty awkward to tip up in place. My complaint is that the two swivel casters have cheesy, weak step-on locks. I found better ones at Lowes for $6/per. The tabs are small and hard to get a sure toe-hold on with work boots. Fortunately, the other two casters have excellent locks, and if you mount them perpendicular to the direction you apply force to the tool, it will not cause problems. I have had no problems with movement from my saw, even when cutting full panels of 3/4 ply. A good choice for roughly the same price of some other kits that require you to supply wood to complete them.

This base was the easiest and quickest to assemble mobile base that I have ever used. Counting the unpacking time it was ready to be used in under 15 minutes. I am using the base for the Jet JWBS-15-3 15 " Bandsaw. It handles the weight very well and is still fairly easy to roll around the shop. It is also a very steady base when the saw is running as well. I noticed other reviews stating that their saw swayed but I didn't have that problem. Of course the Jet JWBS-15-3 weighs over 300 lbs, so that may be what keeps it steady. The only thing I would note is that this was my second shipment of this from Amazon. The first one was missing the side support bars. I believe someone simply removed them, resealed the box and returned it as if it was unused. I don't think it's right to hold Amazon or Jet responsible for that. Besides I had the replacement in less than 2 days and UPS picked up the return so the problem while a little inconvenient, really wasn't that big of a deal.

Well designed, works nicely. Best mobile base I have found. I usually buy the next heavier weight rating base for my recommended load. Weight ratings seem somewhat exaggerated.

I have several of these under my tools. They work great for moving the tools around my garage. I found that by cutting the internal slats I was able to reduce the size to 16.5" which helped with some narrow tools.

Espléndido soporte para la movilidad. Muy recomedable para taller o para usos en casa. Lo estoy usando en mi sierra Knova y ha resultado de gran utilidad.

Great product. Easy and quick to assemble. Roller very easily.
