Bootstrap Farmer's aluminum lock channel and PVC-coated spring wire kit is a complete film retention system for hoop house and greenhouse builders who need a reliable, tool-free method to secure and adjust poly film or shade cloth across seasons.
Made in the USA from rust-free aluminum alloy, the channel bends to follow curved hoop profiles and mounts to wood or steel frames, baseboards, and hip boards. Available in 20-count and 50-count packs. Each channel holds one wire, so applications requiring dual-layer film inflation with two separate wires in a single channel are not supported by this profile.

Whether This System Fits Your Hoop House, Potting Shed, or Multi-Season Greenhouse Setup
If you are building or re-covering a hoop house or greenhouse and want a film attachment system that eliminates nail and staple holes in your poly, allows seasonal film swaps without damage, and works across wood and steel frame types, this kit addresses all of those requirements in a single matched-component package.
The aluminum channel bends to follow the arc of curved hoop structures, with verified field use on hoop houses up to 24 feet wide in circumference. For landscape and commercial operations running large hoop houses, the 50-count pack provides enough channel and wire for substantial coverage from a single order.
The channel cuts cleanly with a reciprocating saw for length adjustment at doors, end walls, and corners. Mounting with stainless steel screws into pre-drilled holes is the recommended approach for clean, straight installation. After the channel is mounted and film is secured, the same channel and wire accept shade cloth in warmer months without remounting, making it a practical two-season fastening solution from a single installation.
What to Expect from the Bootstrap Farmer Aluminum Lock Channel and PVC Wiggle Wire Kit in Real Use
Verified buyers have used this system on hoop houses ranging from small hobby structures to 50 by 20-foot commercial landscape operations. The consistent field report is that the wire and channel hold film securely through significant wind events, with one buyer confirming hold through winds exceeding 40 miles per hour without film movement.
Buyers who previously used nails or staples for film attachment describe the channel system as noticeably faster to install and easier to adjust, with a full greenhouse cover installed in a couple of hours rather than a full day. The channel bends cleanly along curved hoop profiles without tools beyond a straight edge or bending form, and one buyer successfully bent it along a 24-foot circumference hoop house.
Cutting the channel to length with a reciprocating saw is specifically noted as clean and straightforward. The system supports seasonal film-to-shade-cloth transitions using the same installed channel, which eliminates the need to remount hardware between seasons.

Frequently Asked Questions
Can the same installed channel be used for both poly film in winter and shade cloth in summer?
Yes. Once the channel is mounted to your frame, you remove the spring wire and pull the poly film out at the end of the cold season, then lay shade cloth over the same channel opening and press the spring wire back in to secure it. No remounting or additional hardware is required for the seasonal switch.
This makes the one-time installation of channel across your entire structure useful for both heating-season and cooling-season covering without redundant work.
How do you cut the channel to length for end walls, doors, and shorter frame sections?
Aluminum channel cuts cleanly with a reciprocating saw fitted with a metal-cutting blade. A standard hacksaw also works for single cuts. After cutting, deburr the cut end with a file or sandpaper to remove sharp edges before handling or pressing film against the cut section.
For end wall installations where the channel needs to follow a vertical or angled frame member, cutting to the exact length first and then mounting in position is easier than trying to cut the channel after it is fastened to the frame.
Does this channel work on baseboard and hip board positions as well as the main hoop ribs?
Yes. The manufacturer specifically lists baseboards and hip boards as compatible mounting surfaces alongside wood and steel frame members. Baseboard channel is typically the lowest retention point on a hoop house, where the film is secured at ground level before being pulled up and over the structure.
Hip board channel is used at the side wall transition on gothic or tall-sided structures. The same 6.5-foot channel and spring wire work across all of these positions without modification.
