Getting your end assemblies right is one of the most important parts of any fencing job. They’re what hold the whole fence line under tension, so if they’re not up to the task, you’ll know about it pretty quickly. The STAYTIGHT End Assembly range gives you three solid options — Hand-Driveable, Machine-Driveable, and Concrete-In — and choosing the right one comes down to your site, your setup, and how quickly you need the job done.
What to Consider Before You Choose
Every fencing project is different. A boundary fence on flat, accessible country is a very different job to running a fence through steep, rocky terrain with limited machinery and vehicle access. Before picking an end assembly, it’s worth thinking about four key factors: time, site access, the materials and equipment you’ve got on hand, and the overall cost — not just the product price, but the full cost of getting the job done.
Hand-Driveable: The Drive-Tight Post
If speed and simplicity are what you’re after, the Hand-Driveable Drive-Tight Post is hard to beat. It can be installed in under five minutes using just a handheld driver, and the post is immediately ready to strain — no waiting around for concrete to set. The Drive-Tight Post only weighs around 20kg, so one person can carry it to site along with the hand driver without needing vehicle access. That makes it the standout option for hard-to-reach locations, steep country, or anywhere you can’t get machinery in.
The trade-off? It sits at the higher end of the range in terms of material cost. But when you factor in the time, labour, and equipment savings, it can be the most cost-effective option overall. We also highly recommend making use of the Drive-Tight lugs, which require just two short star pickets to complete the assembly.
Machine-Drivable: When You’ve Got the Gear
The Machine-Drivable end assembly is a great middle-ground option. Installation takes around 10 minutes with a pneumatic post driver, and like the Drive-Tight, the post is ready to strain straight away — no curing time needed. It sits in the middle of the price range too, making it a popular choice for larger projects where you’re already running machinery on site.
The key thing to keep in mind is that you’ll need a pneumatic driver powerful enough to drive an 80NB or 100NB post 1,200mm into the ground. Most handheld drivers won’t have the grunt for this, so you’re looking at a decent-sized machine. If you don’t already own one, you’ll need to factor in hire costs. Your site also needs to be accessible enough to get that equipment in and out.
Concrete-In: The Traditional Approach
The Concrete-In end assembly is the lowest-cost option in the STAYTIGHT range when it comes to material price. It’s the method most people are familiar with, and it can get the job done reliably. However, it does require the most time and labour of the three options. You’ll need digging tools or machinery, a concrete mixer, and concrete — plus the concrete needs to cure overnight before you can strain the fence. That means a minimum of two site visits, which adds up in travel time and labour costs.
It’s a solid option when you’ve got easy site access, the right equipment, and you’re not in a rush to get the fence strained. But if you’re working across multiple sites or on a tight timeline, the total cost can climb quickly once you account for the extra time and trips.
Which One’s Right for You?
Compare The Options
Here’s a quick way to think about it. If you need the job done fast with minimal gear and limited site access, go the Hand-Driveable Drive-Tight Post. If you’ve got machinery on site and want a balance of speed and cost, the Machine-Driveable option is your best bet. And if you’re comfortable with the traditional approach and have the time and access to do it, the Concrete-In assembly will do the job at the lowest upfront material cost.

| Time | Drive-Tight posts can be installed in under 5 minutes, and then the post is immediately ready to strain a fence. | The post is installed with a pneumatic driver in around 10mins, then the post is immediately ready to strain a fence. | The concrete needs to be set overnight before a fence line can be strained. Therefore 2 site visits minimum will be required. |
| Materials, Equipment & Specialised Skills | A Drive-Tight Post only requires a hand driver to install and the DriveTight lugs are highly recommended, which require 2x short star pickets. | A pneumatic post driver large enough to drive an 80NB or 100NB Post 1200mm into the ground. Most handheld drivers are not powerful enough to do this. | Digging Tools / Machinery, Concrete Mixer and Concrete. |
| Site Access | You only need to be able to carry a 20kg post and a handheld driver to the site. Best choice for poor site access. | Your site will need to be accessible with machinery and a driver. If travel is required, consider the transportation of equipment. | Must be an accessible area as equipment will be required onsite for digging the post holes and concreting. |
| End Assemblies Cost | This end assembly has the highest material cost but is often the most cost effective as it requires the least time, labour, and equipment of any option. | This assembly is in the middle of our price range however if you don’t own the required equipment the cost of hire must be considered. | This assembly is the lowest costing in our range, however, it takes the most time and labour which will affect the overall cost significantly. |
