Chain Products Sashcord No.4 - Black

Yes, the waxed finish provides water resistance, making it suitable for sheltered outdoor use, though direct long-term exposure to harsh UV rays may degrade the material over many years.

No, 6mm refers to the nominal diameter of the cord in its relaxed, un-stretched state.

The wax helps seal the dye, but we recommend testing a small inconspicuous area if you are concerned about color transfer to delicate light-colored fabrics.

While it is intended for sash weights and home use, it is not certified for industrial lifting or safety-critical climbing applications.

We do not recommend painting the cord, as the wax will prevent the paint from adhering properly and the stiffening effect will hinder the flexibility required for pulley operation.

Ensure the knot is pulled tight while the wax is cool; if the cord is too slick, use a square knot or double fisherman's knot to increase friction.

Check the pulley wheel for rust or debris buildup that may be narrowing the track. Clean the pulley and ensure the cord is properly aligned.

Wrap the end of the cord with a small piece of masking tape before cutting it, then remove the tape after installation or cauterize the end with a flame.
