Master Lock tensioner 6 pieces Jar Red / Green / Yellow 60 x 80 x 100 cm (Tools & Accessories)
The concept is quite nice, you can store your slings at the end of each use. The product and end up very well. the only small thing is the size 60, 80, 100 perhaps it would have been more convenient to have 60, 100.120, but I quibble!
