What tools do I need to install this railing?

We’ll provide all the fasteners you’ll need, including screws for attaching the post to wood and plastic, as well as anchors for cement and masonry. The installation process will be easiest with a handheld power drill or hammer drill, and a set of screwdriver bits — but any set of screwdrivers will work in a pinch. If you need to cut your handrail to size, a cutting tool such as a hacksaw, angle grinder, or die grinder will come in handy.

Can this railing be painted or stained to match my decor?

Absolutely! All our rails come powder-coated with a 5-layer black finish that’s made to withstand even the most extreme weather conditions. This protective layer defends against flaking, chipping, scratches, and color deterioration. Outdoor paint of any color will adhere to the protective layer — in fact, weather-resistant paint can even add an additional layer of defense against the elements, while customizing your rails to look exactly the way you want.

How do I clean and maintain my railings?

Cleaning your rails is easy! Our 5-layer weather-resistant coating already protects against most stains, while dirt is easy to clean off. We recommend following any of the methods below to clean your rails:

  1. Use a non-abrasive or microfiber cleaning cloth dampened with water to wipe and clear the rails from dust.
  2. If using cleaning liquids, we recommend water-based cleaners as these do not damage the finish of the rails. Make sure to dry the surface completely after cleaning to avoid staining and rusting.
  3. If opting for power washing, use the low setting to avoid damage to your rails.

To maintain your railings, we recommend waxing the exposed areas using either commercial car wax or beeswax furniture polish for extra protection and to keep it looking shiny and new. Apply the wax using a soft cloth and rub it gently in circular motions. Allow the wax to dry for at least 20 minutes before buffing it off with a clean, dry cloth.

How hard would it be to build my own rail kit from scratch?

Building a metal handrail from scratch is a fairly time-intensive process, and requires several professional tools. You’d need to start by measuring the height and depth of your steps, as well as the offset distance between the edge of the steps and the post markers. Then you’d need to determine the angle of the rails, as well as the length of each piece of pipe, and buy correctly angled fittings as well as a sufficient amount of pipe. You’d likely also need to choose the correct flanges, swivel fittings, and malleable plugs, as well as fasteners for wood or concrete. After placing the flanges to mark the position of each fitting, you’d secure the fittings to the wood or concrete surface using a power drill, insert the vertical posts, then attach the fittings to the horizontal post and secure it in place.

Building your own handrail from scratch can be a fun weekend project, but our DIY prefabricated rail kits enable you to complete the installation in an hour or less. We include all the components and fasteners, so all you’ll have to do on your end is saw the lengths of metal down to size (if necessary) and secure the components in place.

Should I hire a handyman to install my railings, or do it myself?

All our rail kits are designed to be easy to install in an hour or less. As long as you’re comfortable with using simple power tools, you should be able to handle the job without any special assistance. In fact, more than 3,000 happy customers say their railings were remarkably fast and easy to install!

How can I connect my rails together?

Aside from the instruction manuals that come with all orders, we also have a list of guides that will teach you how to connect your rail kits to each other.

For more info on our instruction guides and videos, you may refer to this page.

I want to install my railings before my connectors arrive. How do I go about this?

Depending on the type of connection and your layout, the distance will vary. However, the tolerance for any discrepancies or errors is only 1/4".

However, we suggest you wait for all parts and rails to arrive before you begin installing the railing system as the top rail positioning will determine where posts will be placed. Once installed, repositioning the posts will require more effort. For the smoothest installation experience, we recommend that you wait for the top rail connectors so you can fit out the top rails and position the posts accordingly.

Do your rails heat up on sunny days?

Like any product made of metal, our rails will heat up a bit on sunny and/or hot days. However, our 5-layer protective powder coating is weather-resistant, and will prevent your railing from becoming too hot to touch. In the unusual circumstance that your railing becomes too hot, simply wiping it down with cold water will quickly cool it off again.

How do I make sure I’m choosing the right option to terminate my Stair Handrails near a wall?

We recommended using this Wall Extension for customers who prefer a more cost-effective alternative. However, the Wall Extension requires that the gap between your Stair Handrail Kit and the wall be less than 4 feet, and that you have a post or wall with structural integrity to attach it to.

If the gap between the Stair Handrail Kit is more than 4 feet or if the wall has no structural integrity, terminating your Stair Handrails with our Horizontal Handrails is the better option.
