DIY 'Polylock' film/fabric fastener system

[Homefire]

 

 

 

Hi everyone,

 

Here is a DIY film locking technique that i have used succesfully in the past.  The trick is to cut the PVC quite accurately & sand the edges off so it doesn't shear the film.

Some testing is advised.  One may use PR 120 both inside and out, it opens easier.  The pipe may be screwed to the greenhouse frame just like store bought polylock.

Have fun.
