Headline: Rubber that outlives seasons
Body: Amazing Straps bungee cords are cut from 100% EPDM rubber and finished with crimped steel hooks, so the strap you tie down in July still pulls tight in January.

Headline: From −104 °F to 248 °F, it keeps its pull
Body: EPDM is the same rubber family used in roofing membranes and automotive seals. It resists sunlight, ozone, rain, hail and snow, so these straps stay elastic outdoors season after season instead of drying out and cracking. Wipe clean and keep using.

Headline: Thicker rubber, firmer pull, hooks that stay put
Body: Each strap is about 30 percent thicker than typical bungee cords and carries a load of over 176 lbs. The 1.8X stretch takes a 21-inch strap to 37.8 inches with firm, even tension — a controlled industrial pull, not a loose snap. Zinc-plated crimped S hooks close around the anchor point and resist rust.

Headline: Four lengths, one rubber
Body: 10 inch for snow chains and short holds. 15 inch for hand carts and racks. 21 inch for truck beds and tarps. 31 inch for oversized loads. Every length stretches to 1.8 times its size with the same firm tension — pick by the distance between your anchor points, unstretched.

Q1. Can these bungee cords stay outside all year in sun, rain and snow?
Yes. The cords are made of 100% EPDM rubber that stays flexible from -104 F to 248 F and resists sun ozone rain and snow so they can stay outdoors year-round holding tarps cargo and equipment without drying out or cracking. (223/250)

Q2. How far do they stretch and how much load can they hold?
Each 21-inch cord stretches up to 1.8 times its length to about 37.8 inches and carries a load of over 176 lbs. The rubber is about 30 percent thicker than typical bungee cords which gives a firm controlled pull rather than a loose snap. (237/250)

Q3. What kind of hooks do they have and will they slip off?
Both ends have zinc-plated crimped S hooks. The crimped shape grips anchor points tighter than open hooks so the cord stays fixed on trailers racks and tie-down rails and the plating resists rust in wet weather. (211/250)

Q4. What are these rubber bungee cords best suited for?
They are built for outdoor jobs such as tying tarps on trucks and flatbeds securing cargo in vans strapping gear to motorcycles and holding canvas over equipment. The same pack also works for everyday indoor fastening. (218/250)

Q5. Do the cords need any maintenance and are the sizes mixed in the pack?
No special care is needed. EPDM rubber is resistant to heat ozone and acids so you can simply wipe the cords clean and check the hooks now and then. This pack contains ten 21-inch black cords all the same size. (210/250)
