Frequently Asked Questions (FAQ)
Q1: Does this mechanism require electrical power or gas pistons to shift?
A: No. The BLS-FB02 is an engineered manual mechanical 4-bar linkage that uses balanced weight geometry for smooth, effortless manual shifting without electrical wiring or maintenance.
Q2: How many hinges are needed per sofa backrest section?
A: For individual single-seat backrests, 1 unit or 1 matched pair is used. For wide 2-seater or 3-seater one-piece moving backrests, we recommend installing 2 to 3 hinges synchronized across the frame.
Q3: What is the MOQ and sample lead time for wholesale orders?
A: Standard MOQ is 300 sets. Free evaluation samples are available and dispatch within 2–3 business days.
