Anchor Applications
For temporary installations, for example at trade shows, the Groundbolt JF range might be more suitable. The JF fittings are permanently screwed or bolted to an accessible part of the shed, with the JF anchors hammered through them as and when the structure needs fixing. The fitting prevents unwanted rotation. To remove them, the anchors are simply unscrewed.
Choosing our low cost anchors.
Park benches and other street furniture are generally secured to the ground, both for safety and to avoid theft. The Groundbolt Erdanker® and JF range of ground anchors provide a very cost effective means of achieving this without using concrete.
Securing benches using JF type anchors
For temporary security, eg at 2 or 3 day trade shows, the Erdanker® JF anchors are ideal. The brackets are permanently fitted to the bench and the anchor hammered through when needed. Removal is by unscrewing the anchor.
The simplest method is to use a wooden spacer and no bracket, as below.

Cross country jumps
How to fix a jump using low profile safety anchors
1/ Fix the T505 bracket to the jump using bolts or large coach screws. The brackets have 6 holes but often 3 or 4 bolts or screws are enough.
2/ When the jump is in position on the course, hammer the anchor through the slot in the bracket. The anchor will rotate, cutting an accurate thread in the ground.
The slot prevents the anchor turning if the jump starts to lift. Removal is quick and easy - the anchor is simply unscrewed from the soil leaving negligible disturbance to the ground. We can supply a spanner but a standard adjustable spanner works well. The anchors can be used and re-used many, many times. 
Easy removal
We offer a removal spanner but any large adjustable spanner can be used.
Additional safety
For the ultimate in safety, and in case the anchor needs to be hidden for aesthetic reasons, we offer an optional rubber cover. The cover clip simply slides under the T505 bracket, taking only a few seconds to fit.
Selecting the correct size and quantity of anchors to fix equestrian jumps
Things to consider:
Is the jump used from both sides?
Is the jump made in 1 piece or 2 pieces?
Soil conditions (hard or sandy)
If the jump is to be used from both sides, it is essential to use anchors front and back (it would be better to have no anchors at all than have them only on the back), the exception is if it's possible to mount them, not on the back or front but in the centre of the sides.
Sturdy single piece jumps can sometimes use 1 anchor on each outside edge (instead of on the front or back), positioned towards the front, lighter jumps are better secured with 2 anchors each side or if very tall, on both front and back. 2 piece jumps need 2 anchors on each side, if the jump is to be used from both sides or it is fairly light, anchors will be needed at the back as well.
