Are you looking to replace your broken bottom Velux Venetian Blind Pins on your Electric or Manual Velux Full Function Venetian Blinds? This is the replacement for the Velux Bottom Pins( one set of a left and one right) that slide into the bottom rail of the Velux Venetian Blind. These Pins hooks into the Side Rail Springs that allow the Blind to go All the Way Up ,Down and Tilt.  Again these Blind Pins are for Both Electric and Manual Velux Venetian Blinds  and If you purchase more than one set you only pay one minimal Shipping Charge.  Thank You
