PRODUCT OVERVIEW:The Pin-End Spring Assist is a device for roller shades which reduces the pull forces required to raise a shade.
When a shade is lowered, gravity is used to coil a spring attached to the pin-end side of the shade. When the shade is raised the coiled spring assists the operator by reducing the pull force required by upwards of 40%.
When used with a RollEase clutch the operator experiences
the smoothest and lowest pull force available on any manually operated shade.
Two sizes: 1.25 (32mm) tube or 1.5 inch (38mm) tube. Left or righ-hand versions for when pin-end on the left-hand side and a version when pin-end is on the right-hand side.
