Operating Chains
- Sold by the meter—cut to your specifications starting at 1 m, e.g., for vertical blind systems or roller shades; the ends are connected using a chain lock, which stops the system by engaging with the gearbox.
- Endless – The product is pre-connected to form a “ring”—e.g., for venetian blinds and pleated shades; these do not have a chain lock and can therefore run “endlessly” through the gear mechanism once installed.
Important when ordering: Diameter of the ball and distance from ball center to ball center
. Please always measure using a vernier caliper (also known as a sliding caliper). Measuring with a ruler or folding ruler is too imprecise for this product. If you do not have a suitable measuring tool available, send us your existing chain and we will find the right replacement item for you.
