"Extension for CareRails Banister Kit and Rail Kit."
Wrought Iron 4'-6" Wall Mounted Stair Hand Rail by William Henry Iron Works, Inc.
"4'-6" long decorative moulding style wall mounted hand rail with three mounting brackets. The rail measures 1 3/4" wide. The clearance between the handrail moulding and the wall is 1 5/8". Unlike other hand rails on the market; all our handrails are formed of 100% solid steel. They are welded at our shop. The volutes (scroll ends) are not welded on they are constructed and built as one piece with the handrail. The brackets are welded on (6" inches from the ends of the volutes) so the rail comes complete and ready for mounting."
