The Plowed Left Hand Volute for the 6010 profile handrail includes the flat rail volute and a 60 degree Upeasing that are plowed to accept wood square top balusters. The easing is a gradual transition that is typically used on straight stairs or the larger radius of curved stairs. It is an elegant fitting that terminates in an inviting swirl atop the starting post at the bottom of a stair. Volutes are one of the simplest methods to upgrade an entire stair and balustrade from typical to luxurious. It is recommended that simple rather than ornate baluster designs, such as iron scroll balusters, are used beneath volutes because these can overlap in the small circular area. As with all of our handrail fittings they are precision manufactured to match our straight and bending handrail profiles. However, because wood expands and contracts at differing rates due to temperature and humidity, expect some sanding to insure a perfect joint.
