About
900 LBS SUPERIOR LOAD‑BEARING CAPACITY This heavy‑duty hidden door hinge is engineered with thickened solid steel and a reinforced alloy steel shaft, supporting up to 900 lbs (400 kg) without sagging. Perfect for massive secret doors, oversized bookcase doors, Hidden door systems, and solid wood shelving – the robust construction ensures long‑term stability even under extreme weight, giving you peace of mind for your heaviest hidden room projects.
360° SMOOTH ROTATION Featuring a unique bearing device, this pivot hinge delivers whisper‑quiet, friction‑free 360° rotation. Whether you’re designing a swiveling bookshelf door for a home library, a concealed cabinet entry in a home office, or a pivot door system for a theater room, the fluid motion and precise positioning enhance both functionality and a premium feel – no squeaking, no sticking.
FLEXIBLE CENTER OR SIDE MOUNTING Install on the central axis for full 360° swing or on the side for nearly 180° inward/outward opening. This adaptability suits secret passageways, room dividers, custom pivot doors, and covert storage – you can tailor the installation to any spatial layout, making it a go‑to choice for DIY enthusiasts and contractors alike.
DISCREET BAFFLE COVER FOR SEAMLESS HIDDEN LOOK The integrated baffle completely conceals the mounting gap after installation, creating a truly invisible appearance. Ideal for secret bookshelf doors, hidden wine cellars, concealed office entries, and private gun rooms – the flush surface blends perfectly with surrounding cabinetry or walls, preserving the aesthetic integrity of your design.
WIDE COMPATIBILITY & INSTALLATION NOTES Compatible with door thickness from 2.4″ to 16″ (60–400 mm) and hinge plate width 2.36″ (60 mm). For proper mortising, remember to reserve 2.6″ at the top of the door frame. If your door thickness falls outside this range, professional installation is recommended. This hinge works excellently with Hidden door kits, swinging shelf doors, panel doors, and custom concealed entries.
COMPLETE HARDWARE KIT INCLUDED The ready‑to‑install package includes: a double‑head screwdriver, 2 woodworking drill bits, 30 mounting screws, 1 door catch, and all necessary accessories – everything you need for a hassle‑free setup. While the kit simplifies DIY hidden door projects, we advise professional help for non‑standard door dimensions to ensure flawless operation.
