Fusion Mk1 and Mk2 spindles

Fusion spindles, also known as balusters, are staircase parts that are produced in two different designs. The difference between Fusion Mk1 and Mk 2 spindles is a common question. Both versions of the Fusion metal spindles look great and will enhance any stairs with their cutting-edge design.

Not sure which Fusion spindles to choose? We can quickly explain the difference between Mark1 and Mark2 Fusion spindles to help you decide which are the best for you and your balustrade. 

Fusion Mk1 baluster

Available in both a landing and an angled stair (rake) version, the Fusion Mk1 spindle comprises a tube made of mild steel with ABS plastic brackets at either end. The brackets can be easily attached to the tube using a single screw. 

Although these brackets are not metal, they are extremely strong. Manufactured from a tough thermosetting plastic called ABS (short for Acrylonitrile Butadiene Styrene), they have been specifically designed to withstand the kind of forces normally associated with landings and staircases, and have passed or exceeded all the relevant British safety tests.

As well as offering strength and durability, the brackets are also designed to bend slightly to allow for accurate positioning on the slope of the stairs. They can be fitted to staircases with an angle of between 38º and 45º.

The baluster tube and brackets are available in both brushed nickel and chrome finishes. They are pre-cut to length, so should not require any modification.

Fixing screws secure each of the brackets to the underside of the handrail and the top of the baserail.

Fusion Mk2 spindle

Available in a stair (rake) and a landing version, the Fusion Mk2 spindle consists of a stainless steel tube with a zinc alloy diecast bracket at each end. The brackets are attached to the tubes by a single screw. 

The metal brackets are of a two-part construction and will pivot to adjust between 38º and 45º to match the pitch of the stairs. The pivot screw can then be tightened to fix the angle, and a cover featuring the Burbidge logo is pushed on to conceal the fixings.

One part of the bracket is delivered already fixed to the spindle (also known as a tube), while the other is supplied loose.

The brackets can be removed from the tube, and the tube cut to length if required. The brackets are then secured to the handrail / baserail with a single fixing screw.

The tube and brackets are available in both chrome and brushed nickel finishes.

The Mk2 balusters, although not identical, are very similar in design and appearance to the Fusion commercial spindles, but they are only currently available with a brushed nickel finish.

Which Fusion spindle is best?

Both types of stair baluster have their merits. The Fusion Mk1 spindle makes an attractive, sturdy yet economical option if your budget is restricted, and looks very similar to its more expensive cousin. The Mk2 baluster requires less assembly and is manufactured mostly from stainless steel, making it a premium choice that's built to last. It also includes stylish metal brackets with the Richard Burbidge logo.

Whichever staircase spindle you choose, you can be sure you'll be getting a good quality product that will enhance your home and last many years. Remember, these spindles can also be used with the elegant Elements range of stair parts if you prefer the square profile over the rounded one.
