New from the Startex Corp. is a locking system for tying plastic sheets together and holding them in place.

The locking device works like a portable zipper. However, instead of zipping together, it uses a rod and tube principle to lock sheets of plastic in place to keep them from being torn by the wind, and to help produce a moisture-proof seal on plastic being used to protect hay stacks, silage piles, grain, machinery or whatever.

Called "Weather Out", the snap together locking system requires no special tools for installation, or for placing or removing the plastic.
