Frequently Asked Questions

Q: What is included in the package?

A: Each order includes 2 × double spring sliding door pulleys. No additional hardware is included, so please check that you have compatible mounting hardware for your door track system.

Q: What materials are these sliding door pulleys made from?

A: The pulleys are made from a combination of thickened steel plate (for the frame) and nylon (for the wheel). This pairing provides excellent pressure resistance, deformation resistance, and smooth, low-friction movement.

Q: Are these pulleys compatible with my sliding door system?

A: These pulleys measure 84 × 78 mm and are designed to fit most standard sliding door track systems. We recommend measuring your current pulleys or track width before purchasing to confirm compatibility.

Q: How does the double spring mechanism work?

A: The double spring design allows the pulley to move elastically up and down along the track, absorbing minor irregularities in the door rail and maintaining consistent contact. The dual springs deliver a stronger rebound force compared to single-spring pulleys, ensuring smoother and more reliable door movement over time.
