Harbor Weight Stack Extender Load Pin

Game Changer

I bought a Smith cage with pulley 2:1 system, so the weight pulled is roughly half the chosen weight. The load pin allows me to add considerably more weight for back exercises. The two sided option is perfect, not like the other one sided only that makes for rougher movement and drag on the plate system. Very happy with this genius product!

Great product

Heavy duty and performs exactly as needed.

Great product!

I have 170lb weight stack with a 2:1 pulley ratio. Needing more weight for some of my movements was a must. Having a dual sided weight extender pinbwas important so I can balance the additional weight and not create unnecessary wear on the bushings/guide rods/pulleys. I also made sure to measure the weight stack hole diameter to ensure the product would fit. And, it is a better price than the competitors! Great product.
