Why it works

Knocked down, straight back up

Self-righting after impact

The HDPE post flexes flat under a vehicle strike and returns upright, with no elastic or rivets to replace.

No bolting down needed

The hexagonal Defiance Base is self-weighted, so the post holds its position without fixings.

Seen day and night

The Starlux pocketed prismatic sleeve gives strong daylight luminance and night-time reflectivity.

Road-legal spec

Meets BSEN13422, The Red Book 2013 and Chapter 8 for use on public highways.

Compatible across the range

The Defiance Base is designed to pair with other Melba Swintex cylinder posts, not just this one.

Frequently asked questions

How does the Defiance Base keep the post upright?

The hexagonal PVC base weighs 8.7kg and is self-weighted, so it holds the post in place on its own without bolting or gluing down.

What heights does the flexi cylinder come in?

460mm, 750mm and 1000mm, all 100mm in diameter and weighing under 1kg each.

What happens when a vehicle drives over it?

The HDPE post flexes flat under the impact and springs back upright on its own - there's no elastic or rivets inside to snap or replace.

Can I use it on public highways?

Yes. It meets BSEN13422, The Red Book 2013 and Chapter 8, with the Starlux sleeve providing the reflectivity those standards call for.

How do I fit the post to the base?

Insert the cylinder into the base and twist it 90 degrees to lock it, then pre-drill a pilot hole through the base into the post and secure with a 35mm or longer self-tapping wood screw.

Will the Defiance Base fit other Melba Swintex posts?

Yes, the base is designed to pair with the wider Melba Swintex cylinder range, not just this post.
