EasyFence Systems Inc. is the sole manufacturer of the Barrier Sleeve (US Patent 7,673,852). The Barrier Sleeve is a plastic tube that simply slides over t-post, rebar, or wood stakes. It has 5 clips designed to hold the plastic mesh fencing used at construction sites, ski resorts or for crowd control. The Barrier Sleeve reduces labor set up and tear down by half. It doesn't rip the fence so the fence can be re-used. Payback is only two uses !
