  • The plate measures 150mm high, 130mm wide, 35mm deep.
  • 2 bolt holes on the main face.  Require 8mm drill bit.
  • 2 bolt holes on the underside for carriage screws. Require 6mm drill bit for pilot hole.
  • The bolts can be tightened using a 13mm spanner.
  • The bolts on the piece that attaches to the straps of your heavy bag require a 17mm spanner.

Additional comments

I bought the brace plate as well – it is used to connect the adjacent joist to the joist holding the main plate (demonstrated below)…

…however my joist beams are not tall enough for the angle that the brace plate sits at once attached so I couldn’t use it.  The brace plate doesn’t actually screw onto the main plate it’s only bolted to the two joist beams just so you know.

The heavy bag I use is an Everlast C3 Heavy foam bag.  It weighs maybe 30kg (66 lbs) and to be fair I think just the RM1000 plate on its own is more than enough to hold the bag safely.

Another point is the 8mm bolts that go horizontally into the plate are barely long enough to go through my joists which are around 45mm thick – especially when you add in the two washer rings.  I’d have preferred longer bolts and if you have thick joists you’ll certainly have to purchase longer bolts separately.

Another thing I forgot was that my joists are all around 35 – 40cm spaced apart which wasn’t enough clearance to get my main drill in to drill the holes!  I had to wait for my smaller hand drill to charge up and use that, so just bear that in mind when you’re installing this plate!

The crazy thing was that including the price for importing the RM1000 from the States and the tax charge of 30 GBP, the mounting plate ended up costing more than my heavy bag!  There’s a spring that helps to dampen the vibration when you hit the bag.  Our bedroom sits above the garage and the floor boards are not very thick so there is still some reverberation when you land your punches.

To be fair, I’m working out in a cellar (to call it a garage is being a bit too generous as there’s barely enough space for anything other than a Smart car!) – a little noise is to be expected.  I certainly won’t be able to work out while my wife is sleeping sadly but I’m still happy.
