Wirelock Base for Greenhouse Poly Covering - 4'

Reliable Aluminum Channel System for Greenhouse Poly Attachment

This 8-foot aluminum wirelock base channel provides a practical solution for securing greenhouse poly covering to your frame structure. Constructed from durable aluminum material, the channel works in conjunction with zig zag wire and 5/16" tek screws (sold separately) to create a secure attachment system for your greenhouse film.

The aluminum construction offers good resistance to rust and corrosion, making it suitable for long-term outdoor use in greenhouse environments. The 8-foot length reduces the number of sections needed for installation while remaining manageable for transport and handling.

Straightforward Installation with Wire-Lock Design

The wirelock channel system uses a proven method for poly film attachment that many greenhouse builders rely on. The channel profile is designed to work with standard zig zag wire, which threads through the system to hold your poly covering in place.

Installation requires basic tools and 5/16" tek screws to mount the channel to your greenhouse frame. This system helps keep poly film taut and properly tensioned, reducing issues with sagging or excessive movement that can occur with other attachment methods. The aluminum material won't crack in cold weather or become brittle from sun exposure like some plastic alternatives.

Durable Construction for Multi-Season Performance

Quality greenhouse components should perform reliably across multiple growing seasons, and this aluminum channel is built with that expectation in mind. The material withstands temperature variations, moisture, and UV exposure typical in greenhouse settings.

When properly installed with zig zag wire, the system maintains tension on your poly covering and minimizes wind flutter that can damage film over time. The corrosion-resistant properties of aluminum ensure that the channels will maintain their functionality without rusting, even in humid greenhouse conditions.

This is a solid choice for both hobby greenhouse projects and commercial growing operations.
