❓ Frequently Asked Questions
Q: What makes this stainless steel trolley better than aluminum pulleys?
A: Aluminum pulleys wear out quickly against steel cables, leaving metal shavings and developing sharp grooves. Solid 304 stainless steel resists friction wear indefinitely, prevents cable abrasion, and is completely impervious to coastal salt air rust.
Q: Can this trolley be used on 5/8" ZIPEAK cables?
A: Yes! Its deep, wide U-groove sheaves are specifically engineered to fit thick commercial cables up to 16mm (5/8"), as well as standard 3/16" and 3/8" residential cables.
Q: Can I attach both a handlebar and a harness to this trolley?
A: Yes. The dual attachment eyelets allow you to clip a primary handlebar/swing seat into the main opening and a secondary safety backup lanyard through the redundant eyelet.
