Yes I would if I was installing the heater into the floor.

I installed a kick space heater into the cabinet of this floor kit. It was nice that it came with a screened register for small debris to not get into the heater element. The floor kit was a really good heavy material. The 1 thing I didn't like was that mounting the heater onto the threaded mount is that it didn't come with any wing nuts or nuts to hold it on; swinging the door on with this unit mounted I felt like I had to be really careful. But works great!

The customer is satisfied I will purchase this product again

Installation is easy as long as the floor joists are 14.5' between not recommended for second floor installs unless 2 X 12 joists

Pricey, sloppily constructed, and poorly packaged...

but it's the only thing that'll do the job, unless you've got the tools and know-how to do your own sheet metal fab work. When this box shows up, the first thing you'll think upon opening it is "I paid more for this metal box than I did for the heater itself??". The second thing you'll think is "oh hey, that's nice, they didn't even bother to package it correctly, so the screw studs for the bottom plate poked through the cardboard box and now they're broken/bent/un-riveted and the accompanying wing nuts are totally mangled". Lastly, when you go to actually install the thing, you'll think "boy I sure am glad they engineered this for a perfect world where the space between 16 inch on center floor joists is EXACTLY 14.5 inches, instead of, you know, maybe shaving 1/8 of an inch of the unnecessary width to accommodate the fact that joists are made of wood and every single one ever made is imperfect". I ordered three of these boxes, one of each for a K42, K84, and K120. Only two of the three came from Supply House, but all three showed up with mangled bottom plate studs due to shoddy packaging at the factory. The only bright spot in this kit is the included register grille, which is surprisingly beefy and sturdy. Buying this kit is a necessary evil if you want to put a BM kickspace heater in the floor, but by god they couldn't have put any less effort into the product or charged more for it.

Still needs tweaking

Skilled MANUFACTURERS will make the unit a bit undersized. No need to make it a *friction fit* between standard joists.

Probably should've hired pros

Skilled framers would have sized it at 14.5

Needs some fine tuning...

I needed to install the unit width-wise in the joist space as it was advertised to be capable of. Typical 16" OC joist spaces provide a 14.5" opening. The problem is the unit is exactly 14.5"- actually just over with the rivet protrusions. Anyone who works around framing knows joist spaces can be off a bit. My 14.25" joist space resulted in a headache to get the unit into place- it turned what should have been a 15 min. install into a 2 hr. ordeal.

Q: Can I purchase the floor kit without the heater? I have a a k-42 I was using under a cabinet now I want to change the cabinet and put the heater under the floor. Is the metal box and grille available without the heater. What would be the numbers and how much would it be.

Part FK42 is the floor kit without the heater. The current picture shows the heater for display purposes, but it is not included.

The floor kit is sold separately. The grill is not the same one that you use with an under cabinet mount and use to be included with the kit. I would go up on the web and pull down the installation diagram to make sure you have proper spacing between the floor joists and depth. I’d also check with the manufacturer to ensure that the K42 you have is compatible with the newer floor mount kit.
