Crank System / Engkol Roller Blind
Engkol uses a geared hand-crank mechanism for manual Roller Blind operation on larger or higher openings. The system offers controlled raising and lowering without a hanging chain, keeping operation practical on spans where chain control becomes less convenient.

System Overview
Geared control. Larger spans.
Engkol replaces looped chain operation with a geared hand crank, making it easier to raise and lower heavier fabric panels across larger or higher openings.

Product Overview
Crank System / Engkol Roller Blind
Hand-Crank Geared Control
Crank System / Engkol Roller Blind
A hand-crank geared Roller Blind system for controlled manual operation on larger or higher openings without a hanging chain.
Turn the crank handle to raise or lower the fabric with geared assistance, reducing the effort needed compared with standard chain operation on taller blinds.
Specify Engkol when the opening is large or high enough that chain control becomes awkward, but motorized operation is not required.
The crank position stays fixed at the installation side, which keeps the window line free of a continuous chain drop.
