This innovative heater hanging system saves time and money.


Manufacturer Recommends Using the Quick-Sling Rafter Mount Heater Swivel Hanging System on Heaters Weighing LESS Than 200 lbs.

(Model QSWI-3000) The innovative Quick-Sling Flush Mount Swivel Heater Hanging System saves you time and money when installing unit heaters. This flush mount system includes an innovative swivel locking wheel, safety hitch clips, locknuts and lock-washers for mounting bracket hardware. It was tested to hold over 500 lbs.

This system is out of the box and installed with a unit in under 5 minutes. All of the installation hardware is included - it comes with pressed-in-stud technology for easy handling, assembly and installation. The unit mounts either parallel with the ceiling joist or straddles two joists either 24" or 32" on center.

Installation time is cut by as much as 90%. No need to create your own unique hanging device from cut unistrut and threaded rod. On single or multiple unit requirements, controlled installation time will make the difference in meeting or exceeding upfront job costing.

This is the only device on the market that allows for 360° of unit rotation. This feature creates directional output accuracy and total flexibility with fuel source and venting requirements. Once connected, the unit locks in place for safety, but offers complete unit access for downstream service by simply unlocking the swivel wheel. Fits nearly all of the unit heaters on the market today (from 18.5" wide to 20.75" wide and 25" long to 27.75" long).

Be proud of the professional appearance created by the Quick-Sling Swivel line. All have a durable powder coating, long-term stable platform, all to provide a consistent, professional look for every installation.

Proudly Made in America!

    Review by on Mar 24, 2017

    I used this to hang my Hot Dawg 75,000 BTU heater (HD75). It honestly probably saved a solid 3-4 hours of work. I'd recommend having an impact drill to get the large stud bolts in easier (it would have been a bit harder if we had to hand crank those things in). I'd also recommend drilling some pilot holes for those studs as they are large. This product is worth every penny. If you were to buy strut, bolts, screws, wood, whatever else to get this hung up otherwise you wouldn't end up too saving a whole lot, but it would certainly take you a whole lot longer.

    Easy installation

    Review by on Dec 8, 2016

    Makes installation a snap, does not come with mounting hardware however. Has three bolts to hook itself together, but no nuts to go with it.

    Don't buy heater without it!

    Review by on Feb 29, 2016

    Made the installation a piece of cake. Needed some help getting the heater up to the mount ( 10 ft.) very sturdy and nice finish. A must I would say.

    A great product and well built !

    Review by on Dec 10, 2015

    This worked perfect with the 45000 btu Modine natural gas garage / shop heater! It made mounting my heater to the ceiling so much easier. You wont regret it when you get started trying to mount the heater to the ceiling in your garage or shop!

    I'm very satisfied with QC Supply, they shipped fast and the Modine heater works perfect and keeps shop at 70deg without any trouble

    Just buy it already

    Good product. Easy to use. Seems sturdy. Would have done 5 stars but the parts bags were all labeled wrong or not labeled at all.

    excellent product

    Review by on Mar 8, 2013

    The quick sling was a lot easier than trying to hold the unit and install lag screws at the same time. I had an issue with one of the bolts striping out due to too much powder coating. I called the mfg direct and they expedited a new part immediately.
