Product Parameter

Product Description

Dual-roller design: Two rollers distribute weight and reduce friction, making doors and windows slide more smoothly;

Metal bracket: Galvanized, rust-proof and with strong support;

Adjustment function: Screws on the bracket (left side of the image) allow for fine-tuning of the pulley height, used to calibrate the sliding clearance of doors and windows.

Product Features

Smoother Sliding: Dual wheels distribute friction, requiring less effort than single wheels and reducing jamming when opening and closing doors and windows;

Strong Load-Bearing Capacity: The combination of dual wheels and a metal bracket can accommodate heavier aluminum alloy doors and windows, resisting deformation;

Good Durability: Color zinc plating provides rust prevention, and the rollers are wear-resistant, ensuring a long service life;

Adjustability: The height can be finely adjusted via screws, facilitating the calibration of door and window gaps and resolving issues with tilting during sliding.
