What Size Acro Prop Do I Need?

Acro Prop Sizes Explained

If you're taking down a wall or propping up part of a structure, getting the right size acro prop is critical. Hire one that’s too short and you’re risking collapse. Too tall — and you’ll struggle to get it in safely.

At ShellCo, we’ve used thousands of props on real sites. Here’s the breakdown:

Prop Size	Closed Height	Open Height	Typical Use
Size 0	1.04m	1.83m	Low ceilings, tight access
Size 1	1.75m	3.12m	Standard ceilings
Size 2	1.98m	3.35m	Knock-throughs & doors
Size 3	2.59m	3.96m	Higher ceilings, extensions
Size 4	3.2m	4.88m	Double-height props, unusual jobs

✅ We stock sizes 0 to 4 — all available for same-day tool hire across Hertfordshire.

How to Measure What You Need

Here’s how to measure:

1. Use a tape from floor to ceiling where the prop will go

2. Add +50mm if placing on timber or packing plates

3. Choose a prop that has a closed range slightly shorter than your height — you want to jack it into place, not wedge it

   
   

Supporting a Wall? Use Strong Boys Too

If you're holding up brickwork during a knock-through, you'll likely need:

• Acro props

• Strong boy attachments

• Sometimes a needle prop (for temporary beam support)
