Bracket accessory for Hikvision electromagnetic lock DS-K4H250-U compatible with DS-K4H250S/D

Bracket accessory for Hikvision electromagnetic lock DS-K4H250-U is a mounting component designed to provide a stable and correctly aligned attachment point for compatible Hikvision locks DS-K4H250S and DS-K4H250D. Manufactured from aldural with a sandblasted finish and hard anodized electroplating on the shell, the bracket supports installation requirements for in-swing doors where the door opens inward to approximately 90°. It is intended for use with the 300 kg series magnetic locks and ensures mechanical compatibility and durable surface protection for door hardware installations.

Advantages

The bracket is made of aldural material and features a sandblast surface treatment that improves corrosion resistance and provides a uniform appearance. Hard anodizing electroplating on the shell increases surface hardness and wear resistance, extending service life in typical access control environments. The design is suitable for in-swing doors that open inward to 90°, and it is engineered to match the dimensions and mounting requirements of 300 kg series magnetic locks from Hikvision, facilitating correct alignment and reliable holding force transmission.

Suitable for

• Mounting Hikvision DS-K4H250S and DS-K4H250D electromagnetic locks on in-swing doors
• Door hardware installations requiring a bracket for 300 kg series magnetic locks
• Applications where inward door opening at approximately 90° must be accommodated

Key specifications

• Material: aldural
• Surface treatment: sandblast finish
• Shell finish: hard anodizing electroplating
• Compatibility: designed for 300 kg series electromagnetic locks
• Door type: suitable for in-swing doors opening inward to 90°

How to use

Position the bracket on the door frame so that it aligns with the mounting points of the DS-K4H250S or DS-K4H250D lock. Secure the bracket to the frame using appropriate fasteners for the frame material and ensure that the magnet face will be flush and parallel with the armature plate when the door is closed. Verify that the door opens inward to approximately 90° and that the bracket does not interfere with the door swing. After mechanical installation, perform alignment checks and tighten all fasteners to the recommended torque values before applying power to the electromagnetic lock.

Usage recommendations

Use corrosion-resistant fasteners appropriate for the mounting surface, verify compatibility with the 300 kg series magnetic lock before installation, and check alignment regularly. For installations in corrosive or outdoor environments, consider additional protective measures to maintain bracket and lock performance.
