Spacer Blocks - Box of 48

Product ID: 7392

Allows two layers of greenhouse film without an electric blower.

Saves electricity and makes this type of application practical in remote areas without electrical power. Used between two layers of plastic to maintain an insulating dead air space, which helps improve the thermal properties and increase light diffusion in your structure, which in turn improves crop quality and yield. To determine how many you will need, measure the width of your plastic from hipboard to hipboard, if applicable. Spacer blocks should be placed 2-3 ft. apart on every bow except the end-wall bows and really no closer than 2 ft. from the gathering point on the hipboard (or baseboard, if no hipboards exist). Each block includes two tie wraps. Made in USA.
