Secret Door Hardware Kit, Heavy‑Duty Hidden Cross Hinges for Bookcase Hidden Door

Description

• 3D ADJUSTABLE HIDDEN DOOR HINGE — Features a 3-way adjustable mechanism: vertical ±2.5mm (up/down), horizontal ±3mm (left/right), depth ±1mm (in/out). Unlike standard hidden hinges for doors that lock you into one position, our 3D adjustable concealed hinge lets you fine-tune door alignment after flush mount installation — no need to remove the hinge or re-cut mortise slots.

• HEAVY DUTY CONCEALED HINGES FOR WOOD DOORS —Silent Smooth‑Rolling Bottom Casters, 200 kg Load Capacity for Moving Doors. Crafted from solid zinc alloy with a corrosion-resistant matte black finish, this heavy duty concealed hinge is built for solid wood doors, thick doors (min. 40mm), and interior doors that demand long-term durability — without sagging, loosening, or squeaking.

• INVISIBLE HINGE — ZERO CLEARANCE WHEN CLOSED — Completely invisible when the door is shut for a seamless, frameless look on both sides. Opens to 120° for easy passage through the hidden door, secret door, or bookcase door. The zero clearance design makes these invisible hinges for doors ideal for projects where both aesthetics and function matter. • Designed for flush mount mortise installation on wood doors and frames. Each set includes slotting dimensions and step-by-step instructions so both DIYers and pros can install with confidence. Includes all hardware: 2 concealed hinges, screws, and hex wrenches — everything you need.

• BUILT FOR HIDDEN DOOR PROJECTS — From secret bookcase doors to bookcases and wine cellar entries, this versatile hinge kit works for a wide range of applications. Whether you’re creating a secret passageway, a trap door, or a fully concealed bookshelf door, this hardware is designed to deliver seamless, invisible operation.
