Quick video showing you how to secure items with a ratchet strap and how to release once done.
The ones I used were purchased from Amazon: amzn.to/3L3NIUb
The straps are mainly used for securing loads in vans and lorries, pallets, roof racks, trailers but their use is endless. I used mine to clamp together a table-top that I was gluing.
Some people also know ratchet straps as webbing straps, cargo straps or lashing straps.
