Product Description


Surface Mount Universal Top 2″ Square Posts provide the foundation for a cable railing system.

Our cable railing posts are available in multiple material types (304 Stainless Steel, 316 Stainless Steel & Aluminum), and in multiple finishes (Brushed, Powder Coated Black, White, Pewter & Copper Vein). All holes are drilled with 3.125″ spacing, and we recommend putting a post at least every 4 feet to reduce deflection and ensure that you meet code. Guide to getting started with Viewrail.

"S" Cable Railing Post

“S” – The “S” post is shipped without any holes pre-drilled in the post itself (handrail bracket and foot still come pre-drilled). Select this post if you have an application where cables are necessary but you still want to run handrail, or in a custom application and you want to drill the holes yourself.

* All offset holes are drilled at 40 degrees (the typical angle of a staircase), these 40 degree holes work with angles between 36 – 42 degrees. If you staircase falls outside those angles custom hole drilling can be requested at no additional charge.

Posts are manufactured 1″ shorter than their defined height. This will allow you to be at the exact height with our 1″ tall metal handrail, or slightly over with our 1 5/8″ tall 6000 series handrail.

Mounting feet come with 4 holes (6 holes on “B” posts) for 3/8″ fasteners. The handrail bracket also comes with 6 pre-drilled holes to secure the handrail.

The standard brackets that come with our posts are designed to work with flat bottom handrail, if you order our Round Metal Handrail 2″, we’ll automatically select rounded brackets to work with the handrail. If you have round wood handrail, or are ordering an additional post for your project please specify in the notes if you need a rounded bracket.

The stainless steel posts are a hand polished stainless steel.  The finish is created by with an American worker and polishing wheel working with the steel products. The finish is polished to a bright finish with enough polishing lines to give character to the light as it reflects off. Here is what our customer’s say, “High quality” … “Beautiful Finish” … “Very Durable.” Posts are pre-drilled with 3.125″ spacing to accommodate our cable railing system. Custom hole drilling can be requested. Mounting feet with 4 holes are provided for 3/8″ fasteners. They can be fastened to concrete or wood with the 4 mounting holes provided at the bottom of the mounting feet.   Since there is a such a wide scope of fastening situations, fasteners are not provided.  Angle posts have holes drilled at a 40 degree angle which will accommodate most stairways from 37 degrees to 42 degrees. They can be ordered as 3-way and 4 way with holes on 3 sides or 4 side of the post to allow for creating right angles from posts.

    Base plate dimensions?

    Support
    2 years 1 day ago

    Hi Mark,
    The base plate (or post foot), is 3 3/4″ x 3 3/4″. The thickness varies based on material. Aluminum feet are thicker than steel & stainless steel to ensure the posts are structurally strong enough.

    Let us know if you have additional questions.
    Thanks,

    hello, I am building a cable rail between two walls 14’10” wide. if I put a 2″ post 4″ from wall and one in middle using 3 posts the span between each post would be aprox 80 inches, is that ok or do I need four posts? (aprox 54″)

    Support
    1 year 8 months ago

    Hi Ross,
    We strongly recommend that you put a post at least every 48″ (therefore we’d suggest you use five posts). You need that many posts to reduce the deflection of the cable, if you put your posts 80″ or 54″ apart it is very possible that you won’t pass code.

    Can I paint the posts?

    Support
    1 year 6 months ago

    You could definitely paint the posts if you’d like, but it won’t be as durable a finish as the powder coating we offer. If you are looking for a specific color we can do custom powder coating colors.

    Your post video shows a “G” post configuration for a corner post, but I don’t see that as an option. Can a “G” post be ordered as I would much rather have that than the “C” configuration that is available.

    Hi Rachel,
    The “G” post configuration has been eliminated in order to simplify our system. However, if you need it for your project you can order online and then call in to add that custom item, or you can place your order over the phone.
    Please let us know if you have any other questions.

    Hi Rob,
    That is a style of post we used to offer called a “Flat Top” post. We’ve moved now to only offering the “Universal Top”. However if you’d like to place a special order for them we could make them for you. Please let me know if you have any other questions.

    Where its says, “handrail height”, is that the distance from the floor to the top of the handrail bracket, or to the top of the wooden handrail? What is the actual height of the level posts from the finished floor (bottom of the base plate) to the top of the handrail bracket? What is the spacing of the pre-drilled holes?

    Support
    1 year 3 months ago

    Hi Frank,
    The “Handrail Height” refers to the finished height, from the bottom of the foot to the top of the handrail. On Metal handrail it would be 36″, on wood handrail it would be 36 1/2″.

    On a 36″ post, the height from bottom of the foot to top of the bracket is 35″. Standard hole spacing is 3 1/8″.

    If you need more technical information like this a good resource for you would be our Viewrail Buyers Guide.

    Please let us know if you have any other questions.

    Hi I am adding a rail on top of a 24″ half wall to meet code for which i need 42″. Can I cut your 10 hole 36″ posts and if so is it from top or bottom? thanks

    Hello,
    We can easily custom make these posts for you. Instead of a 36″ tall post with 10 holes, we could make you 24″ tall posts with 6 holes. Just send us the exact specifications, and we can custom make them for you.

    What are dimensions of the top plate to which handrail attaches, and distance between the centers of the screw holes? Will it fit the handrail that is 1-1/4″ at the base?

    Support
    1 year 2 months ago

    Hi Alex,
    The width of the bracket on our cable rail posts is 1 3/4″ wide. I’d recommend getting a wider handrail, as the handrail provides a significant amount of the strength of the system.

    Is that the “Standard Post Bracket – Straight PC: Black- SRSM-10096, for use on top of cable railing post with flat bottom handrail, including machine screws for attaching to post dome” ? This was listed on a quote received, but looking on the website for the part number did not find it listed. The price on the quote was $0.00, so is it automatically included or does it have to be specified somehow when adding to the online cart?

    Support
    7 months 30 days ago

    Yes, the brackets are included at no charge. Once you place your order, we separate them onto their own line item so that we can easily pull them. And it allows us to more easily specify if the bracket needs to be bent to accept a round handrail. When you order online we review your order and add those at no charge.

    Aluminum is a great choice for outdoor applications, especially if you’re wanting to use a powder coated finish.

    The posts are manufactured to the exact same specifications, but the only difference is the direction that the included bracket turns. If you would require the opposite direction of bracket, they are available for purchase separately.

    We’re looking to have fewer cables than the 10 pre-drilled holes would seem to require. Any advice on whether it is do-able to just string the cable thru every other hole? If it’s been done before and you have photos of a finished product, could you send along to us? Thanks!!

    9 months 3 hours ago

    Thank you for contacting us Jeff. Although it is likely that this has been done with our product before, we recommend following the most widely accepted code requirements of spacing between openings to not be more than 4 inches. Thus, we would not have project photos outside of those recommendations generally available. We would welcome the chance to learn more about your specific project. Please email us directly at orders@stairsupplies.com, and we will be more than happy to assist you.

    Do the aluminum posts look different from the stainless steel posts if they are powder coated black?

    Thank you for contacting us, Steve. We can certainly look at custom post options for your specific need. In this instance, we would recommend that you send your project-specific information to us directly at saless@stairsupplies.com for us to review your unique need. Regarding the powder coat question, we would not anticipate any significant difference in the overall look of a powder coated post whether it is manufactured out of aluminum or stainless steel.
