This castor is designed for use on smooth to semi-smooth indoor surfaces such as concrete, vinyl, laminate, and sealed timber floors. The hard polypropylene wheel rolls efficiently on flat, dry surfaces and is well suited to retail, warehouse, and workshop environments. It is not recommended for outdoor use or heavily uneven terrain. How does the brake mechanism work on this swivel castor? The castor features a side-operated integrated brake that locks the wheel in place when engaged, preventing unwanted movement during loading, unloading, or stationary use. The brake is operated by foot or hand pressure on the brake lever and releases just as easily, making it practical in fast-paced working environments. What are the top plate fixing dimensions for this castor? The 4-hole pressed steel top plate measures 60 x 60mm with hole centres of 48mm and 38mm and a hole diameter of 6mm. These dimensions are standard across many trolley and equipment frames, making this castor a straightforward replacement or upgrade component in most applications. Can this castor be used as a direct replacement for an existing unit? In most cases, yes ? provided the existing mounting plate matches the 60 x 60mm plate with 48/38mm hole centres and 6mm hole diameter. Always verify the total castor height of 122mm against your equipment clearance requirements before fitting, and confirm the load rating is appropriate for your application. * All specifications are per individual castor unit. Maximum set load of 255kg is based on a standard 4-castor configuration and assumes even load distribution. Always verify suitability for your specific application prior to installation.
