The door track is bolted through the lower batten and the lintel after the Polytunnel has been covered. Care should be taken when drilling the lintel so that the polythene under the second batten is not torn. In the case of a double sliding door, then two rails need fixing using a steel joiner which are slid approximately half way into the tee slot on the rear of the track, centralised and tightened up with grub screws. To prevent the door from catching on the pleats of the polythene, extra battens are nailed vertically to the outside of the door post and then horizontally to the outside of the sliding door support. The Polytunnel in this video is 10ft wide x 15ft long (5ft hoop spacing) If you would like to discover more about Poly tunnels then why not contact us at www.FirstTunnels.co.uk or join our Facebook group at www.facebook.com/polytunnels
