This adjustable spring butt door hinge is intended for swing-door assemblies that require an integrated closing function. Spring hinges use adjustable internal tension to influence how a door returns toward the closed position. The product has two equal rectangular leaves, five round fixing holes on each side, and an enlarged four-section barrel with narrow contrasting rings. Knurled end caps and a directional arrow marking provide visible reference points for setup, while black, gray, silver-tone, and gold-tone versions are shown.
Before sourcing, confirm the mounting dimensions, hole centers, leaf thickness, hinge orientation, opening direction, profile connection, and required load target. Buyers should also define the desired closing behavior and adjustment method, because these details cannot be established from the exterior geometry alone. Finish samples should be approved against the complete door hardware set.
For quotation review, send a dimensioned drawing or physical sample, door and frame construction, hinge quantity per door, installation position, opening direction, finish reference, closing requirements, order quantity, and packaging instructions. CHIER can then assess the barrel arrangement, ten-hole pattern, and requested installation format for OEM or ODM development.
