Ultion Bolt IUB48RK 48mm Roller Keep

The Ultion Bolt IUB48RK 48mm Roller Keep is a high-quality adjustable bolt roller keep engineered specifically for multipoint locking systems, providing reliable performance and improved door alignment. Designed for use on composite and timber doors, this deadbolt keep is particularly suited for installations where a slightly deeper keep is required, ensuring optimal engagement between the lock and frame.

With a robust construction measuring 144mm in length and 18mm in width, this Ultion bolt keep offers a universal handing design, making it suitable for both left and right-handed doors without the need for modification. The integrated rollers are a key feature of this product, helping to improve door compression which results in a tighter seal, reduced draughts, and a quieter closing action. This makes it an excellent choice for homeowners looking to enhance both security and comfort.

Manufactured by Ultion, a trusted name in door security hardware, this adjustable roller keep ensures durability and long-term performance. Its precision design supports smooth operation of the multipoint locking mechanism, reducing wear on internal components and helping maintain consistent locking performance over time.

To keep your multipoint locking system performing at its best, regular maintenance is recommended. Applying a high-quality lubricant such as GT85 to the gearbox and moving parts will help reduce wear, prevent stiffness, and extend the lifespan of your lock.

Whilst upgrading your multipoint door lock keep, it is also the perfect opportunity to enhance both security and aesthetics. Consider upgrading your door cylinder to a high-security 3 star cylinder for improved protection against snapping and forced entry. At the same time, replacing your door handles can give your door a fresh, modern look while ensuring full compatibility with your locking system.
