USE OF ‘P’ CLIPS 

 

 

The image below demonstrates the 

double

 ‘P’ Clip method used to fix the Triple Ridge. 

 
 

          

 

 
 
The following images show how a Corner Stabiliser or any tube flattened and punched at the end attaches to a ‘P’ Clip.  
 
 

NOTE: 

‘P’ Clips should always be placed around a hoop so that the leg of the P is to the inside of the polytunnel – That 

is to say, as far away from the polythene cover as possible. 
 
 

      

 

 
 
 

***PLEASE NOTE: When assembling your polytunnel, no screws, bolts, ends of tubes, etc, should protrude beyond 

the hoops as these will cause damage to your cover***
