Easy to use:
It is recommended that tie down kits are used to secure marquees in all but the calmest of conditions.
The spiral anchor is designed for use with marquees and used by the military, this is Lloyds tested to 150kg in wet grass which is screwed into the ground next to the base plate, the cargo strap is then looped through the spikes handle and around the eaves beam (these are not the cheap dog stakes).
This will then secure your marquee without the need for hazardous guide ropes on the out side, which in the dark provide a significant tripping hazard.
Budget Tie Down Kits are for use at 45 from the marquee eaves poles and consist of the same ratchet strap attached to a straight 1.5 ft spike.
