Heavy Duty 30 x 2 inch Cinch Strap, Black, 5 pack

title reads 48 x 2 inch and "Technical Details" reads 11 x 10.2 x 0.8 inches, please tell me what the size is.

I need to hang a 50 lb Kayak with these straps - Will your straps hold this weight? Also are there secure loops on each end to slip them securely?

Price ($29.66) and item weight (8.41lb) seems high for just one strap, is it more than one? Asking about the 3”x36” strap.

How many straps come ?
