My friend and I installed my 4 Point Harken Hoister for my JKU (which works as it is intended) but he stated that he'd prefer to be safer and have:
1) 'rope tie-off' anchor point to avoid accidental rope slippage if 'block' fails
2) additional safety ratchet strap(s)
He's not the one with the Wrangler Unlimited, but he said if it is was his vehicle he'd add some additional safety measures and not rely on the 'ball bearing block system' to save the top crashing down.
Anyone construct additional safety measures (post pics if possible) or just rely on the 'block'? Are his worries unwarranted
