Frequently asked questions

Everything you need to know before you buy.

The Pro Post Leveler is available in three sizes to cover the most common post profiles used in balustrade and fencing installation:
  • 42.4mm round — standard glass balustrade handrail tube
  • 48.3mm round — common balustrade and fencing tube
  • 40mm square — standard box section post
If you're unsure which size your posts are, check your product specification or measure the outer diameter of the post tube.
Yes — the Pro Post Leveler was specifically designed with glass balustrade installation in mind. Getting posts perfectly plumb is critical for glass panels to sit correctly and for the system to look professional. It works with the standard round and square post sizes used in most glass balustrade systems. If you're sourcing posts and components for a glass balustrade project, suppliers like DIY Balustrades carry a wide range compatible with all three leveler sizes.
Both. The Pro Post Leveler is simple enough for a confident DIYer tackling a home balustrade or decking project, and robust enough for daily trade use on site. It's compact and fits easily in a toolbox or van shelf. We also offer trade and reseller pricing — use the "Trade / reseller enquiry" button on this page to get in touch.
A standard spirit level needs to be held against the side of a post, which means checking two directions separately and holding it steady while you work. The Pro Post Leveler sits on top of the post and reads plumb in multiple directions simultaneously, leaving your hands free to adjust and fix the post. It's faster, more accurate, and far easier to use solo.
One leveler is all you need — it simply moves from post to post as you work along a run. Many trade customers order two or three so multiple installers can work simultaneously on longer jobs. Quantity discounts are available via the trade enquiry form.
Orders are dispatched fast — typically the same or next working day. Delivery is via tracked courier to mainland UK addresses. If you need to confirm lead times for a large trade order, get in touch via the trade enquiry button above.
