MINVEE American SUS304 Stainless Steel Hydraulic Soft Close Frog Hinge (No-Boring Bridge Hinge)
Product Overview
The MINVEE American SUS304 Stainless Steel Hydraulic Frog Hinge (commonly known as a bridge hinge or surface-mount hinge) offers a practical solution for cabinet door mounting. Engineered with a zero-boring design, it eliminates the need to drill standard 35 mm hinge cup holes, allowing direct surface screwing onto cabinet panels. Constructed from SUS304 stainless steel and fitted with an upgraded solid brass hydraulic cylinder, it provides rust resistance and silent, slam-free soft closing for modern kitchen, bathroom, and office furniture.

Frequently Asked Questions (FAQ)
Q1: What is a “Frog Hinge” (Bridge Hinge), and when should I use it instead of a cup hinge?
A: A Frog Hinge (or bridge hinge) mounts directly to the surface of the door and cabinet frame without requiring a recessed 35 mm cup hole. It is ideal for thin doors, glass door aluminum profiles, RV/boat cabinetry, or DIY furniture repairs where cup boring equipment is unavailable.
Q2: Why is SUS304 stainless steel critical for hydraulic frog hinges?
A: Standard iron frog hinges can rust quickly at the pivot joints and hydraulic cylinder, leading to squeaking or failure. SUS304 stainless steel resists moisture and salt spray, making it suitable for damp kitchen environments, vanities, and marine applications.
Q3: Does this frog hinge support soft-closing action?
A: Yes. Built-in brass hydraulic cylinders catch the closing momentum and gently pull the cabinet door shut silently during the last phase of closing.
Q4: What packaging and OEM customization options are available for wholesale orders?
A: Standard packaging includes industrial bulk master cartons (200 pcs/ctn) with stainless steel screws included, or individual polybags. Custom logo laser marking on the hinge body and branded master carton printing are available for OEM buyers.
