What is code for cable deck railing?

Most state and local codes require railing posts to be 36 inches tall for residential applications. If you’re in California, they require residential posts to be a minimum of 42 inches tall.

How far apart are posts for cable railing?

4-feet apart
Spacing the posts properly Unless homeowners are using additional support, posts should be no further than 4-feet apart. This is done to ensure cables do not deflect or bow under cable tension loads. By placing posts 4-feet apart homeowners ensure their cables will still meet the 4-inch sphere rule.

Are cable deck railings safe?

From a structural standpoint, today’s cable railing systems are some of the safest and most durable guardrails available. Due to the novelty and increased popularity of these systems, cable railings have at times been held to tighter standards than traditional vertical picket railings.

How far can you SPAN cable rail?

Never exceed a spacing of 60” between posts. For each foot over 4 feet that you run cable, you must move your cable 1/4” closer together. For example, the cable spacing would be 2-3/4” for a cable span of 5 feet.

How tight should deck cables be?

The short answer is: Tight enough to pass code, which in most areas is tight enough to ensure a 4-inch sphere does not push through the lines easily. The Key to cable railing is cable spacing and the spacing between support posts.

Do cable railings sag?

Cable that stretches easily under tension, will sag over time resulting in unhappy clients and code inspectors. If your cable railing is considered to be a guard, you will also need to make sure that no opening is large enough to allow the passage of a four-inch sphere.

Do cable railings meet code?

Since cable railing does not have the same rigidity of steel balusters or wood, it can defect (open up) when pressure is applied. To meet code requirements, the cables should be installed close enough together to ensure that a 4-inch sphere can’t pass through even if the cables are stretched.

Do cable railings need a top rail?

A top rail is always necessary when building a wood railing with cable railing infill. The top rail should always be installed to absorb and deflect the pressure applied when cable is tensioned. It is highly recommended to secure the top rails between the post rather than simply placing the rail on top of the posts.
