These 2 1/2″ wide wood porch spindles represent our “midsize” option. A very versatile size, they can used on small or large homes and porches alike with success. This is our 2nd-best selling spindle, behind only the 3 1/2″ Porch Spindles.
Actual Width: 2 1/2″. Specify length. Turned portion is 15″ long, centered in the spindle. Bottom notch option reduces length by 1/8″.
Use with either our 6″ or 4″ class Porch Rail Systems.
Spacing & Quantity: To meet the 4″ ball rule required by most building codes, space these spindles every 5 1/4″ On Center. The smallest diameter of the turned portion is approx. 1 3/8″, so with a 5 1/4″ O.C. spacing, you’ll have a 3 7/8″ gap between them at the narrowest portion. To determine quantity required, take your rail length in inches and divide by 5.25.
