The flat top allows you to select any type of Newel Post Cap to finish the post. If you wish to have a turned cap such as a ball or acorn cap then you will need to purchase a flat cap to fit on the post first then fit the ball or acorn.

The complete type newel has been designed for new build staircases or to replace your entire newel post.
Complete Newel posts are supplied in two profiles, each with it specific purpose on a staircase.
The full 90mm x 90mm Full Newel - This is the most commonly used post on most stair configurations. It is designed for the bottom of the stair case, top of the staircase, used as mid posts and corner posts on a landing.
The 90mm Half Newel Post - Used up against a wall to finish the handrail run. This post is fixed by screwing and gluing it directly to the wall using suitable fixings. Screws should be positioned so that they are hidden from view by the handrail.
Fitting Square Newel Posts
Newel Posts are fitted first followed by base rails and handrails.
Remember that handrail heights need to be 900mm.
The bottom post is housed over the stair string (the side of the staircase) and fixed into position fixing through the side of the post and through the string using tapered dowels or suitable wood screws. Screws should be countersunk into the timber so they can be plugged or filled to match the timber.
Top posts and landing posts are fixed using a lap joint to the joist under the floorboards at the top of the stairs and secured using suitable wood screws. Remember to always drill pilot holes into hardwoods.
You can use Zip Fix UT Newel Post fasteners if you prefer. These secure the post to concrete or timber sub floors.
Half newel posts are glued and screwed directly to the wall. Place the screws through the head of the post where the handrail will cover them.
We recommend laying out your stair components to ensure handrail heights are 900mm before you cut any existing newel posts.
