How to choose the best stairlift rail

If you’re considering a stairlift, one of the first things to think about is how it will fit on your stairs. How is the rail secured? How far does the rail stick out past the bottom stair? What is the rail length? Can it go around corners? What if you have a door at the bottom and need the rail to fold up and out of the way?

There are several factors to take into account and it can be difficult to know where to start. Fortunately, we’ve got you covered! In this article, we’ll highlight the different types of stairlift rails, their dimensions and how their various features and options can help make your home safer.

Types of Stairlift Rails 

On a basic level, there are three main types of stairlift rail: straight, curved and outdoor. Each of these rail types is suited to a different type of staircase and the rail type you’ll need will depend on where you want to get your stairlift installed. Let’s take a closer look, so you can figure out which rail option is best for you.

Straight Stairlift Rail

The most common staircase is straight making the straight rail the most popular. Straight rails are mass-produced and cut to length to fit on your staircase. They’re typically silver or bronze in color and made of aluminium. The best rails will be anodized and scratch-resistant. 

In terms of your straight staircase’s dimensions, the only real concerns are stair width and head clearance. As long as you have sufficient head clearance for the user and your stairs are a minimum of 28” wide, installing a straight stairlift shouldn't be a problem.

Straight Rail Dimensions

Straight rails are fitted with a charging strip that provides a constant charge, powering the stairlift’s battery, regardless of where you decide to park the chair. The rail itself only sticks out about 6” onto the staircase, leaving plenty of room for others to get by. Contrary to popular belief, the rail is fixed to the stair treads, not the wall. This is much more secure and causes far less damage to your home, as it doesn't require any major modifications. It typically requires just a few screws to attach the legs to the treads on every other stair. The only other important factor to consider is that the rail will likely stick out around 18” at the bottom of the staircase, so the stairlift has a place to land. If you have a door or walkway at the bottom, you might need to consider some additional options.

Powered Folding or Retractable Rail Option

The Retractable Rail Option, also known as hinged rail, is the perfect solution for obstructed landings at the bottom of a straight staircase. The rail folds up and down with the push of a button, clearing space at the bottom of the stairs and providing a safe landing for your stairlift on the ground floor. Once you’ve disembarked, you can send the stairlift back upstairs remotely and the retractable rail will fold up and out of the way, until you’re ready to use it again.

Curved Stairlift Rail

If your stairs make a turn, have an intermediate landing or include multiple flights, you’ll likely need a curved rail stairlift. Curved rails are more complicated than straights. They have to be custom-made to handle the bends and turns of your stairs while maintaining a smooth and level ride. Unlike straight staircases, where the stair width is relatively consistent, curved staircases often include pie-shaped stairs and variant widths that need to be accounted for.

Curved stairlifts can be installed on either side of the stairs making an inside turn or going around an outside bend. Regardless of which side you choose, Stannah will take precise measurements to design a custom-made rail to fit perfectly on your staircase. Luckily, there are usually a variety of solutions and options. You can choose everything from the color of the rail to how and where the stairlift starts and finishes.

Types of Curved Rails

There are two major types of curved stairlifts: modular and custom-made. As their names imply, one is custom-designed for your stairs, while the other is composed of pre-fabricated parts that are assembled into a completed stairlift rail.

Custom Curved Rails

When choosing Stannah, our consultant will measure your stairs, and then we will design, manufacture and install custom rails / bespoke rails that are a tighter fit and offer a smoother ride. The twin-tube design is popular, but the characteristics of the rail can vary, depending on the company you choose.

Modular Curved Rails

Modular rails, meanwhile, are often single tube and boast a quicker delivery time. However, the ride quality isn’t as smooth as a custom rail and it is important to note that if you have a complicated staircase with very tight turns, you might need a tailor-made rail to fit precisely your staircase.

Curved Stairlift Rail Dimensions

Curved rail dimensions vary depending on the specifics of your staircase. Because each curved staircase is different, it’s hard to give approximate dimensions for stairs that turn. Long, straight sections can have rail protrusions that are similar to the 6” typically seen on straight stairlifts, but it’s difficult to say how far the rail will stick out where it makes corners. However, bespoke rails are known to hug turns significantly tighter than modular stairlift rails.

Curved Stairlift Rail Charging & Power

Unlike straight rails, curved rails do not offer a constant charging strip. Instead, they have to meet a silver spring charging point at the top or bottom of the stairs. Only then, will the stairlift’s batteries receive the charge they need. If you park your stairlift away from the charging point, you will hear a beeping noise, alerting you that your stairlift is not charging. It’s important to keep your stairlift charged, so it’s always ready for use. Otherwise, you might need to have them replaced.

Curved Stairlift Rail Starts & Finishes

Sometimes, there isn’t a convenient place to park the stairlift at the top or bottom of the stairs. That’s where alternative curved rail starts and finishes come in handy.

For example, a 180° turn and park is a common example of an alternative rail start. That means at the bottom of the stairs, the rail turns and bends around a wall or banister, so that the stairlift can be parked and folded up out of the way.

Similarly, an over-run finish at the top of the stairs is an example of an alternative rail finish. Rather than finishing level with the top riser, the curved rail can continue onto the landing, either finishing flat on the top landing or bending around a corner, so as to be even further away from the stairs.

These are just a few examples. Many other types of rail starts and finishes can be installed, depending on your home’s interior design and your physical needs. If you need a curved rail but want to preserve space at the bottom of the stairs or park the stairlift away from the staircase at the top, make sure to ask about alternative rail starts and finishes during your home visit.

Outdoor Stairlift Rails

Finally, let’s talk about rails for outdoor stairlifts. While some companies do carry curved outdoor stairlifts, outdoor rails are typically straight (as most outdoor staircases are). Like, indoor straights, they are cut to length and relatively straightforward in nature. However, unlike indoor rails, they’re sturdily built to withstand fluctuating weather; rain, snow, salt air, and wild critters won’t stop this rail from getting you out and about. While there are few options for outdoor stairlift rails, this is a genuine four-season product: resilient, reliable and built to last.
