Cable & Glass Railings in Baltimore, MD

Why People Choose Them

Cable and glass railings exist to disappear. Stainless cables strung between posts, or tempered glass panels in a frame or base shoe, keep a stairwell, loft or roof deck open where balusters would read as a wall. They suit modern interiors, renovated rowhouses with roof decks, and decks on lots with something worth looking at. They also cost more than balusters and need precise installation, which is why they are quoted from a measure, not a photo.

Cable: Tension Is Everything

A cable railing has to meet the same 4-inch sphere rule as any guard, and it has to meet it under load, when someone leans on a cable or a child pushes between two. That depends on cable spacing, post spacing and the tension the end fittings hold over time. Intermediate posts or spacers keep spans short enough. Cables can run horizontally or vertically, and that choice matters in one place in particular.

The Baltimore City Question

The model residential code says nothing against horizontal infill, and we have found no similar clause in the counties around the city, though not every county supplement has been read end to end. Baltimore City's version of the code appears to add that required guards may not be built with horizontal rails or any pattern that creates a ladder effect. That reading comes from a summary of the City code and has not yet been confirmed word for word, so for a required guard in the city we recommend asking DHCD first, or using vertical cable or glass, which avoid the question. In Perry Hall, Towson or Severna Park horizontal cable is generally an option where it meets the sphere rule; confirm with the county permit office if in doubt.

Glass

Glass guards use tempered or laminated safety glazing, which the code requires in guards, mounted in a base shoe or clamped to posts. On a stair they still need a graspable handrail 34 to 38 inches above the nosings, usually mounted to the glass or the posts. Glass and cable pair well with wood handrails inside, and an older open stair may need a code upgrade anyway. For a traditional porch, iron or aluminum is usually the better fit.

How long does it take? Cable and glass systems are made to measure, so there is a gap between the measure and the install. The install itself is usually a day or two.
