The SPY453 Pleated Curtain Cream Cord Tube Hexagonal Pin Spool (Left) is a left-sided cream-colored spool used for cord collection in pleated curtain systems. Thanks to its compatibility with both hexagonal and square pins, it can be easily used in various curtain systems. It fits reinforced top rails with a 10 mm channel width. The tube-shaped spool winds the cord by receiving motion from the tilt mechanism, raising the curtain. For optimal performance, a minimum of 3 spools per meter of curtain is recommended. It can be used together with the SPY452 right-sided tube spool and SPY447, SPY446 chain mechanisms. The product is sold without cord; the cord must be supplied separately.
