Leave the shrink wrap on until the blind is fitted. Measure between the bracket fixing holes and mark the position level and slightly off centre, so the mesh sits central in the opening. Drill and bolt the blind up, then fit the chain guide and thread the chain around the wheel, joining the ends with the supplied shackle. Pull down to mark and fix the C brackets for the bottom bar, then mount the locking box on the post to lock the chain and tension the blind. Drops over 4.2m also take aluminium side channels for health and safety. A full fitting guide is supplied with every blind.

The problem

Big openings are the hardest to weatherproof.

Large doorways and bays let wind, rain and snow straight through. A fixed screen is not always practical. A hand chain blind lets you close a big opening down in controlled stages and open it back up for airflow. With animal welfare a priority, you protect livestock without closing the building up completely, for happier, healthier stock.

Handles a big doorway easily

Covers a 4m bay and the chain makes it light to operate. Stops the rain blowing straight through the building.

George M.LancashireVerified

Side channels were the right call

They advised side channels for the drop and it is rock solid in the wind. Good honest advice.

Hywel T.CeredigionVerified

Solid bit of kit

Well built and operates smoothly. Fitting took two of us but that is to be expected at this size.
