Unlike smaller props used in confined areas, the size 2 acrow prop is engineered to handle broader working heights without sacrificing stability. It is commonly selected for projects where flexibility is essential, such as extensions, refurbishments, and structural alterations. The combination of an inner sliding tube, outer casing, and adjustable collar allows for controlled extension, while the locking pin secures the load in position. This balance of reach and strength makes it one of the most widely used prop sizes on-site.

Frequently asked questions
What is the extension range for size 2 acrow props?
Size 2 acrow props can be adjusted from approximately 1.98m to 3.35m, suitable for standard floor-to-ceiling heights in many commercial and residential builds.
How much does a size 2 acrow prop weigh?
Approximately 20kg, requiring careful handling but still practical for site use.
What applications suit size 2 acrow props best?
Ideal for supporting beams, slabs, and formwork in multi-storey construction, or where medium-tall temporary supports are needed at heights of 2–3.35 metres.
What should I know about load ratings for size 2 acrow props?
Safe working loads are significant at lower heights but reduce towards full extension. Use manufacturer charts to ensure loads stay within limits (typically 15–35kN range).
How important is vertical alignment for size 2 acrow props?
Critical, maintain within 1.5 degrees of plumb to maximise load capacity and safety at these heights.
Are size 2 acrow props compatible with U-heads or other accessories?
Yes, they work well with various head attachments like U-heads for bearer support or flat plates for distributed loading.
When would a contractor select size 2 acrow props over size 1 or 3?
Choose size 2 acrow props when your required propping height falls squarely in the 1.98m to 3.35m range for optimal strength and efficiency.
Tips for safe use of size 2 acrow props?
Always use on stable ground with sole plates, avoid side loading, and never use damaged props. Regular inspection of the pin and collar is essential.
