Hook stakes can be driven in the ground to avoid tripping hazards to provide a safer environment around your inflatable unit. These can also be used with camping tents, pop up tents and any smaller structures. Hook stakes are made from steel to strongly secure inflatables and last through multiple seasons of use.
