Gradus Aluminium Movement Joint 2.5m MJ304SF4

Gradus Aluminium Movement Joint 2.5m MJ304SF4 

The Gradus Aluminium Movement Joint 2.5m MJ304SF4 is a high-quality flooring profile designed to manage expansion and contraction within rigid floor finishes. Suitable for use with materials such as ceramic tile, marble, stone, terrazzo and resin systems, this movement joint allows controlled movement of up to 1.5mm, helping to prevent cracking, edge damage and surface failure over time.  

Manufactured from durable aluminium with an integrated silicone joint, the MJ304SF4 combines structural strength with flexibility. The aluminium support legs provide a stable fixing base, while the central silicone section absorbs movement between adjoining floor sections. This ensures long-term performance in environments subject to thermal or structural movement.  

Designed for 10mm floor coverings, the profile is installed during the flooring process and should sit flush with, or slightly below, the finished surface for a clean and professional appearance. The perforated base allows for secure fixing into the subfloor, ensuring reliable installation and stability.  

Ideal for commercial, industrial and high-traffic environments such as retail units, healthcare facilities and public buildings, the MJ304SF4 provides both functional performance and edge protection. Its anodised aluminium finish offers resistance to wear and corrosion, making it a durable, low-maintenance solution for internal flooring applications where movement control is essential.
