Features

POLY VENT®

Thermostatically controlled Poly-Vent natural venting system is a modern alternative to more expensive rack & pinion vents. This system provides an air-tight seal on both top and bottom for the full length of the greenhouse. It will open as the thermostat calls for ventilation. The POLY VENT® wall acts as an insulator with it's dead air space when fully inflated.

WIGGLE-WIRE

Used on thousands of greenhouses, WIGGLE-WIRE has proven to be a low-cost, effective way to attach polyethylene or shade material to greenhouses. The base is easy to install and bens readily over any hoop configuration. Multiple layers of plastic and shade cloth can be installed and moved without disturbing the plastic lock. The single base can even be used on end hoops instead of the common "twin" spline type of locker.
