Body Solid Olympic Adapter Sleeve 14"

Plastic seems fairly dense so it's not flimsy. Uses a small allen screw to tighten on the bar it's fixed to. Was nice to see the appropriate allen key included. The top comes off with some light persuasion if you need to shorten the tube. I'd happily recommend this product.

This sleeve isn't quite like I expected it to be - a solid tube with outer 2 inches and inner 1 inch in diameter. (approx 1.2cm thick plastic)Instead its a tube with approx 0.5cm thickness with 6 'spokes' pointing in towards the centre of about 3mm thickness.Whilst it converts 1 inch to 2 inch it remains to be seen if it is infact fit for (my) intended purpose.I wouldn't expect any problems converting the loading bar of a machine as the forces are not directly on the spokes.However, as I intended to use it on a barbell for lifts such as deadlift/bent rows etc I am not sure how its going to last with the force fully against the spokes when hitting the ground (not dropping)
