Cap & Rack Spring Roller

The Cap & Rack Spring Roller is a traditionaldesign which has been used for many years, butdeclined in recent years as it has two design faultswhich make it unsuitable for use except in anenvironment where it will be used withconsiderable care. We do not recommend its use,unless it is particularly required for historicalaccuracy or to match existing blinds.

Problems: The pawl in the cap action is permanently in contact with therack as the blind is drawn down, causing clicking noise and resultant wearin the mechanism. The second problem is when allowing the blind to rise,the side release cord must be held until it has come to stop. If the cord isreleased, the pawl will engage the rack at speed which leads to damage ofthe mechanism.

Operation: The blind is drawn by pulling on the centre cord until therequired position is reached (holding down the side release cord duringthis procedure is recommended). To raise the blind the side release cord ispulled allowing the spring to roll the blind up and stop when the cord canbe released. When raising and lowering the blind both cords must be heldto guide the fabric.

Construction: A metal barrel is fitted with nylon end blocks and containsa helical coil spring. The action has a polished brass cap (always mountedon the right hand side of a normal roller blind) containing the rack andpawl lever both in steel.
