Bootstrap FarmerSidewall Manual Hand Crank Winch for Greenhouse Ventilation

When I recovered my 30x40' greenhouse this year I added a roll up sidewall using one of these units. Very simple to install and works great. It makes a HUGE difference in daytime temps having the sidewall up, drops the temp by at least 20 degrees having the extra airflow, wish I would have done it earlier.

Very happy with the fact that you are not only concerned with the quality of your products, but there is a real effort on your part to insure customer satisfaction. We received the hand cranks (2) well packed and in good condition. Included with instructions as well as a PDF to our email with installing this product.Well done!Thanks :)Sophie

I installed these on a 30' x 130' greenhouse. The sidewalls are 5-1/2' high. One crank on each sidewall is enough to easily lift the entire length of poly. I have only had them installed for a week or so, but so far, I highly recommend them.

Love the bootstraper. Worth its weight in diamonds.Easy installation, works much better than expected.Spend time with plants, not greenhouses.Living high in Colorado. Bootstrap did good.

Good product, but the directions were written in a language I can't even begin to read and there weren't pics to help..got it set up though, and it works..

Good Price, Easy to install and works very well on my hoop house, So much easier than the hand crank. I would recommend this to everyone.

These were easy to install and came with great instructions.

Pricey but works great

Item works OK, 2 stars was given because the seller takes your money and buys the product on aliexpress (confrim by courier) . Except importing fee of 15$ extra.
