Size 3 is one of the taller props in the range, used on both domestic and commercial jobs where you need to prop beyond the reach of a size 1 or 2. Typical work includes supporting floor slabs and roof structures, holding beams and lintels during installation, and giving temporary support to frameworks. Because capacity falls as the prop extends, plan the number and spacing of props around your actual working height rather than the closed rating, and always set them plumb on a firm, spread base.
Dimensions
| Specification | Measurement |
|---|---|
| Closed Height | 2.59m |
| Extended Height | 3.96m |
| Outer Tube Diameter | 60.3mm |
| Inner Tube Diameter | 48.3mm |
| Weight (Approx.) | ~22kg |
| Base Plate Size | 150mm x 150mm |
| Safe Working Load* | ~34kN near closed, reducing to ~7kN fully extended |
*SWL reduces as the prop is extended and depends on loading conditions. Always confirm the required capacity for your application with a competent person or structural engineer.

Frequently asked questions
What heights can this size achieve?
Size 3 acrow props adjust from about 2.59m to 3.96m, designed for taller support requirements in larger construction projects.
What is the weight of a size 3 acrow prop?
Weighing approximately 22kg, they are sturdier and may benefit from two-person handling on site.
What are the typical uses for these size props?
Perfect for higher floor slabs, commercial building formwork, temporary wall supports, and applications needing propping above 2.59 metres up to nearly 4m.
How does extension height affect load capacity in size 3 acrow props?
As with all props, capacity decreases with greater extension. At maximum height, SWL is lower, so plan your layout accordingly using the load chart.
What are the installation considerations specific to this taller size?
Pay extra attention to base stability and verticality. Use adequate sole plates and consider load distribution at the head.
Can they be used in raking shore applications?
Yes, with proper pivot adapters and brackets, they can provide effective angled support for walls or formwork in their height range.
Why select this size for your project?
They offer the right combination of reach for heights up to 3.96m without going to the largest and heaviest size 4.
What should be checked before using these acrow props?
Inspect the inner and outer tubes for straightness, ensure the thread and collar are in good condition, and verify no signs of overloading or damage from previous use.
