Specific notable features of this staircase:
this snapshot shows the difference in height of the newel that is achieved by the use of a curved arm style of volute instead of a standard volute. This allows for a lower point of leverage, thus strengthening the entire balustrade. Safety is enhanced by keeping the rail within easy reach of a larger percentage of the population.
This gooseneck fitting combined with an up-easing is the standard method of making the transition to a landing rail from a raked rail in an "over the post" design such as this one.
This alternative method is reduced to a simple over-easing fitting, by positioning the landing newel a few inches back from the last riser.
To maintain the smooth curvature of the railing in this particular curved staircase, this fitting needed to be hand carved. Compared to a gooseneck, this custom connection increases the cost by roughly $120.00. Typical straight and curved staircase designs allow for a standard factory produced over-easing reducing the overall cost of this connection by roughly $60.00
This alternative method provides the user with a continuous ergonomic gripping surface, as well as eliminating a sharp 90° corner formed by the gooseneck fitting, making the egress environment safer to navigate.
