This was made for a 50W machine but may fit others. This was designed to fit a RECI W1 tube which is 1100mm with an 80mm diameter.
The box is a flat pack design , the mounting flange is 18mm all round and will require drilling to fit. When assembled the cover is extremely strong being made of 1.6mm steel,
Not sure exactly what the steel is but it is extremely resistant to corrosion.
The socket head machine bolts and nyloc nuts are stainless steel.
Cost is £20,
The parts weigh around 2.5Kg hence the P+P of £8 but collection From Wakefield is welcome.
