NEWELS Newels serve as the main structural support of the balustrade portion of the stair. Proper placement, coupled with proper installation techniques, is critical to a structurally sound and code compliant staircase. Newels should be placed at the top and bottom of every stair, at all directional changes, and at intervals of not more than 8' on level balcony runs
PTP newels are designed with upper (top) square blocks that will receive the handrail.   STARTING NEWELS A 5" top block will always work at the beginning of the stair. Larger top blocks are unnecessary and can and can heavy.
Intermediate landing newels will have angled rail entering and exiting the upper square block from adjacent sides. Because the newel is basically making up for two rise dimensions in the stair, a longer square block is necessary to keep consistent rake rail heights from the first run to the second. A newel with a minimum 13" top block will be required.
Balcony newels will have angled rail entering from the lower side of the newel with level rail exiting from the top of the upper block. You could use the same intermediate newel or even a 10" to block should work.
Balcony intermediate newels will have level rail entering and exiting the upper block of the newel. A 5" top block is recommended.
