I have 2 olympic weight trees.
Both are made in USA and are VERY heavy Duty trees and can quickly hold over a 1000lb each.
1) made by Parabody and has 8 weight horns and a holder for clips.
2) made by Nautilus in is a A-Frame style, extremely tough and has holes to be bolted to the floor. The photo shows a 45lb plate(not included), to reveal its size.
Cost is $100 per tree.
If you see the advertisement, theyre readily available and if you have any concerns feel complimentary to ask.
