Rollercam Spider System Cam-Strap Tie-Down Kit
Rollercam Spider System Cam-Strap Tie-Down Kit
The Rollercam Spider System is a six-arm cam-strap kit that pins an odd-shaped load down to a rack or platform from one center point. The hub measures 13 x 19 x 0.67 inches, and six 1-inch loop-end straps run off it at 6 feet each. Anchor the arms out to your rails or rack corners, set the load in the middle, and pull each strap down. A single over-the-top strap lets a cooler or fuel can rock and walk; the Spider holds it from every direction at once.
Each arm runs the Rollercam buckle. You tension it by hand, then snug it tighter after the load settles. There is no ratchet handle to feed wrong and no clamp to slip. The cam holds against road vibration and trail chatter, and a thumb press drops the tension when you are done. Working load is 350 pounds per strap, built on a 3:1 safety factor.
The webbing is high-tenacity polypropylene with UV inhibitors, stitched with triple-bar bar-tacks and T-135 polyester thread. The roller is marine-grade brass; the cam body is corrosion-resistant Zamak 2 with stainless springs and shafts. Built for roof racks, cargo platforms, and raft frames. This is a soft-goods and gear system rated 350 pounds per strap, not a freight ratchet for rigid loads like lumber.

The Rollercam Spider System secures an awkward load to a rack or platform from a single center hub. Six 6-foot cam straps radiate from the hub so the load is held from every direction instead of one strap fighting the whole job.

What comes in the kit?
Six loop-end straps, 6 feet long and 1 inch wide, plus one central Spider hub measuring 13 x 19 x 0.67 inches. The straps run off the hub so one anchor point holds a load from several directions.
How much can each strap hold?
350 pounds working load per strap, built on a 3:1 safety factor. With six arms sharing the load, that covers most coolers, cans, and gear bags.
How is the Rollercam buckle different from a ratchet?
You tension it by hand and release it with a thumb press. There is no ratchet handle to feed backward or over-crank, and the cam re-tensions so you can add bite after the load settles.
Will it loosen from road vibration?
The cam holds tension under vibration and trail chatter. If the load shifts on a rough stretch, you can snug each arm tighter from the center without unloading anything.
What can I strap down with it?
Odd-shaped soft and hard loads: coolers, fuel and water cans, dry bags, and gear totes on roof racks, cargo platforms, and raft frames.
Is this for heavy freight like lumber?
No. The Spider is a soft-goods and gear system rated 350 pounds per strap. For rigid, heavy freight, use a freight-rated ratchet strap instead.
How do I keep it in shape?
The marine brass roller, stainless hardware, and UV-treated webbing shrug off sun and weather. After a dusty or sandy trip, rinse grit off the roller so the cam keeps rolling clean.
