Cundy Peel Round Strainer Post, UC4 Treated, Pointed, 2.4m x 125-150mm

This cundy peeled round strainer post is made for the end, corner and support positions of post-and-wire and stock fencing, where the fence needs strength and stability. It is slow-grown European redwood, peeled rather than machine rounded, pointed at one end, kiln dried and pressure treated to Use Class 4 for ground contact. It suits farmers, smallholders and fencing contractors. You can buy it at 2.4m long in a 125-150mm diameter. The 3m length in 150-175mm diameter is currently unavailable. Diameter varies along each post.

Why it works

Peeled for a stronger strainer

Cundy peeling roughly cuts the pole and scrapes the bark off, instead of turning it down to a set size on a machine. Because the peeling process does not change the intrinsic nature or shape of the timber, the result is a stronger strainer than one that has been machine rounded. The finish is rustic and natural.

Treatment for ground contact

Posts are kiln dried, then pressure treated to UC4, the use class for timber in contact with the ground. The peeled surface allows better preservative penetration than machine rounding, and the pine lets the treatment reach the heartwood. That gives a protective barrier through the post against fungal decay, rot and insect attack.

Pointed for installation

Each post has a pointed end for ease of installation. At 125-150mm across and 17kg per post, this is a much heavier section than a line post, so plan how you will handle and set it.

The honest limitation: diameter varies

Because the post is not machine rounded, its diameter is not uniform along its length. The 125-150mm figure is a range, not a fixed size, and one end may be noticeably thicker than the other. Allow for this if fittings or tools need an exact diameter. The expected lifespan is about 15 years, but that is an expectation rather than a guarantee; many factors affect how long a post lasts.

Where it's used

Strainer posts go at the ends, corners and support points of post-and-wire and stock fencing runs on farms, smallholdings and paddocks. This post is intended for use with stock fencing, welded wire rolls and panels, chicken and rabbit wire, and straining line wire, fixed with galvanised staples or U-nails. Between the strainers, slimmer line posts carry the netting or wire.

Specifications

Choosing the right option

Use a strainer post wherever the fence starts, ends, turns a corner or needs extra support, and use line posts for the run in between. The strainer is the heavier section. This post is 125-150mm in diameter and is designed to provide strength and stability, while the matching cundy peeled line posts are a slimmer section for the line.

At present the only size you can order is 2.4m long in 125-150mm. The 3m length in 150-175mm is currently unavailable, so plan around the 2.4m post if your design calls for something longer or thicker. Strut sizes, bracing and spacing between strainers are not published for this line; follow your fence design or your contractor's specification.

Installation, use & care

Use the pointed end to start the post straight. Items listed for use alongside this post include a post hole digger, a post hole rammer and fence post cement, so a dug hole that is rammed or cemented is an option as well as driving. At 17kg per post, a second person helps keep each strainer upright and in line. Cut tops to height once the post is in, and treat any cut surface with a suitable timber preservative. Weathering from green to silver-grey is normal.

FAQ

What is the difference between a strainer and a line post?

A strainer is the larger end, corner or support post that gives the fence its strength and stability; this one is 125-150mm in diameter. Line posts are slimmer and fill the run between strainers.

Why is the post thicker at one point than another?

It is cundy peeled, not machine rounded, so it follows the natural shape of the pole. Diameter varies along its length within the stated range. Do not expect a uniform, lathe-turned post.

Can it go straight into the ground?

Yes. It is pressure treated to Use Class 4, the class intended for ground contact, and the treatment penetrates to the heartwood against fungal decay, rot and insect attack.

How long will it last?

The expected lifespan is about 15 years. That is an expectation, not a guarantee. Soil, drainage, installation and cutting all affect it.
