Customize your greenhouse or high tunnel with high-integrity hardware. Choose a Poly Latch system to secure plastic to supports without the hassle and degradation issues of furring strips. Roll up sidewalls with more ease, make your tunnel mobile, or install a second layer of film or plastic. Johnny’s carries trial-tested greenhouse hardware products, whatever your needs.
