Strongman 125mm, 1200mm lift, MR06 125mmm, 1090mm lift.

The strongman unit appears to have 12 or so locking positions as opposed to 4 on the MR06. Neither requires a compressor as Strongman's latest one now has manual unlocks.

The Strongman one is well over £300 more expensive.

Interesting Strongman advise 6in of concrete in the floor to operate thier unit.
