Our 9 Gauge barbed staples are used for fixing our fence fabric to trees or wooden posts.
The large staple is driven into the wood with 1/2 inches protruding to leave room for the mesh to move between the top of the staple and the wood.
These staples are usually very hard to obtain in small packs as they are normally sold in large 50lb cartons.
TIP
When using with polyamide cable leave 1/2 inch of staple protruding to enable the cable to slide under the staple.
