Straight Drop Blinds are your entry level blind for those on a budget. The blind has 2 options for operating. The first is Spring Loaded – which means the blind needs to be held, pulled down and locked into tie down points and to retract you need to hold the bottom bar and lift as it retracts. The spring loaded blind is suited to openings up to approximately 3m. Over that width for ease of use, you would go to the second option of Crank Handle. This works with a handle attached to a gear box in the main tube, you simply wind the crank handle to move the blind up or down. When the blind is in the down position it needs to be locked down to the tie-off points. The Crank Handle blind can span to 6m in width.
