Raytech Onyx Mag 4 - 115VPut the power of magnetic finishers to work for you! Magnetic finishing remains todays state of the art method to finish precious, non ferrous metals with a high degree of intricacy with medias (stainless steel pins) as small as 0. 30mm in diameter and 0. 25mm in length. Magnets embedded in a cast disc constantly change polarity, creating a centrifugal action in the media allowing your finisher to access recesses, channels, undercuts, and other

Put the power of magnetic finishers to work for you! Magnetic finishing remains today’s state-of-the-art method to finish precious, non-ferrous metals with a high degree of intricacy with medias (stainless steel pins) as small as 0.30mm in diameter and 0.25mm in length.

Magnets embedded in a cast disc constantly change polarity, creating a centrifugal action in the media allowing your finisher to access recesses, channels, undercuts, and other confined areas where other conventional methods/medias simply cannot. Soft, non-ferrous metals can be burnished in as little as half an hour, ensuring quicker turnaround time and improved productivity. If your pieces have large, smooth or flat surfaces, the finish will appear frosted or have an interesting, satin-finish look. A slight buffing or a run in a dry finisher (such as our 852-0746) will easily bring the finish to a high shine. 

The Onyx 4 utilizes a direct-drive, fan-cooled motor providing a variable speed, forward/reverse function to change the direction of media flow and thus not allowing the stainless steel pins to clump in one area of the bowl.

The Onyx Mag 4 comes complete with a heavy-duty plastic bowl/cover. It can accommodate an 8-12 ring capacity and comes supplied with ample amount (250 grams) of 0.5mm stainless steel pins, as well as a supply of burnishing compound to keep your pins and parts running as clean as possible.

One-Year Warranty. Made in Taiwan.

Features:

  • Direct-drive, fan-cooled machine for ultra-quiet operation.
  • Auto shutoff function.
  • Clear bowl with fill-line indicators offer easy load preparation of pins and compound (See Related Products for Replacement Bowl).
  • Space-saving finisher is fully programmable. Additional features include an electronic timer with a digital readout
  • Compact heavy-duty construction for long life usage.

All Raytech Magnetic Finishers are built and engineered to the highest quality standards.

Awesome quality
Color: White, Color: White
Take your time installing! It comes with all the instructions and templates. Make sure you’re screwing this into solid wood. I would not recommend you hang your expensive PC from a particle board table. My Pc fits in well and it’s compatible with a ton of different sizes. Mine has been mounted under my desk for about 6 months and is rock solid. I will say, mine is balancing in there. If I don’t have it at its center of gravity, it could tip out. You can adjust it with the various screw holes but make sure you mount it into something solid.

PC holder that looks great and works on large PCs for easy under desk mounting
Color: Black
After a lot of research and trial and error I finally found the Heavy Duty Under Desk PC Holder. It is the only under desk PC holder that looks good and is able to hold my HP Omen 45L where I want it - under my desk. Putting it together is relatively easy as was the installation to the desk. No messing with cables or round steel tubes to get the job done. The metal is solid, the black powder coating looks great, and the installation hardware is a;l there including a drill bit, hex key, and wrench. You just need to bring a screw driver for the wood screws to attach it to your desk. Read the instructions and make sure you take the depth of your PC into account when attaching the PC holder to your desk, especially if you have a standing desk with motors.

Quality Holder
Color: White
Very quality holder and very sturdy and stable. I purchased it back in April, and it has been holding up nicely. I would definitely say that it is worth the price. I love that it's adjustable, so if I ever decide I want to new PC case, I can still use it (as long as it fits the dimensions of the holder). Putting it together and mounting it was simple. The only reason I'm giving 4 stars is that it did not come with screws, and I had to purchase some. I hope that has been changed since then.

Awesome holder. Follow the directions. This appears to be German manufactured and very well thought out. Great having my rig off my desk - more room for my second monitor!
