The BoSS non-tyred castor wheels are key components of mobile access towers, enabling easy repositioning without the need for disassembly. With a bright yellow polymer wheel mounted in a durable aluminium adaptor, these castors provide smooth rolling and enhanced visibility for improved safety.
- 150mm (6 inch) Castor (32842300): Compact design with an overall open height of approximately 0.19m, perfect for standard tower setups and tight spaces.
- 200mm (8 inch) Castor (32942300): Larger wheel diameter and an overall open height of approximately 0.24m, offering better clearance and smoother movement over uneven surfaces or minor obstacles.
Both models are built to BoSS’s high standards, ensuring seamless integration and long-lasting performance with your existing BoSS tower system.

Product FAQs
What is the difference between the 150mm and 200mm BoSS non-tyred castors?
The primary differences are wheel diameter and overall height. The 150mm (32842300) offers a lower profile (~0.19m open height) for standard applications, while the 200mm (32942300) provides greater ground clearance (~0.24m open height) for better performance on slightly uneven floors.
Are these castors compatible with my BoSS tower?
Yes, both models are designed for use with all BoSS Ladderspan, Clima, 700 Series, and Zone:1 GRP scaffolds, including both aluminium and fibreglass (GRP) towers.
What does “non-tyred” mean?
Non-tyred castors feature a solid polymer wheel without a separate rubber or pneumatic tyre. This design is puncture-proof, low-maintenance, and suitable for smooth indoor surfaces or controlled environments.
Do these castors include brakes?
Yes, both BoSS non-tyred castor wheel sizes come with an integrated safety brake that locks the wheel and secures the tower during operation.
How do I know if a castor needs replacing?
Inspect regularly for cracks, damage, or wear on the wheel, adaptor, or brake mechanism. Replace immediately if any damage is found to maintain safety and tower stability.
Can these castors be used outdoors?
The BoSS non-tyred castor wheels are best suited for indoor or smooth outdoor surfaces.
