Product FAQs
What is the primary purpose of this product?
It is designed exclusively for levelling BoSS mobile scaffold towers on uneven or sloping ground and for connecting castors or base plates. It helps maintain a stable platform, enhancing safety.
Can I use adjustable legs to increase the overall height of my tower?
No. Adjustable legs are for levelling only and should never be used to gain extra working height. At least one leg must remain at minimum extension for safety.
How much adjustment does this leg provide?
The open length is 0.624m, offering a practical adjustment range of 250-300mm, depending on configuration, suitable for most uneven surfaces.
Is this compatible with castors?
Yes, the castor-style design allows secure attachment of BoSS castors (sold separately) for mobility.
Which material is it made from?
It is constructed from high-grade aluminium for strength, durability, and lightweight handling.
Are there any usage restrictions?
Always follow BoSS assembly guides and EN 1004 regulations. The BoSS adjustable leg assembly is intended to level the tower on slightly uneven ground, provided the surface is firm, stable, and load-bearing. The tower must be fully levelled and inspected before use.
