FAQ

Q: How do I replace the insert when it wears?
A: Most NHD13 profiles use a snap-in or screw-retained insert. Remove the fixing screws (if present) or pry out the worn insert per the manufacturer’s instructions, clean the channel, then fit the new insert and secure with screws or adhesive as specified. Always follow the supplier’s installation guide.
