Adding weight to very light doors
In general, when the roll-up door is very light, a number of symptoms may become
apparent and cause temporary malfunctions of the product. These include stopping
after moving short distances and not closing completely. In these cases, it is
necessary to add weight to the bottom edge of the door curtain. The recommended
way of adding weight is to affix a length of angled steel to the bottom edge of the door
curtain as shown:
Angled Steel
Aluminum door edge

The angled steel is attached directly to the aluminium edging of the door curtain with
tek screws. Depending on the door type, other screws may be used. The steel is
mounted on the inside of the door i.e. the side facing the inside of the garage.
Once weight is added to the door, it may need adjustment. Ensure that
the door is consistently easily lift-able once the weight is added.
Use short screws, long ones may damage the rubber at the bottom of the
door curtain.
