Key Features & Enhancements

Exact Fit Replacement: Directly replaces the 4-hole "butterfly" winged guides found on brands like Crestline, Vetter, and SNE.

Premium ASA Material: Unlike the original brittle plastic, these are printed in ASA for superior UV resistance and weatherability in exterior house window applications.

Heavy-Duty Construction: Printed using a 0.6mm nozzle to create thicker, more robust extrusion lines, significantly increasing the shear strength of the "wings" and mounting pins.

Heat & Stress Resistant: Designed to withstand the constant tension of window balance springs and the high temperatures of direct sunlight without warping or snapping.
