Two choices of mounting bar:
Mounting bar for elongated toilet (compatible with small and medium HTS): Elongated toilets will measure more than 17" from the centerline of the seat bolts to the front edge of the porcelain bowl.
Mounting bar for round front toilet (compatible with small, medium and large HTS*): Round-front toilets will measure 17" or less from the centerline of the seat bolts to the front edge of the porcelain bowl.
Use the mounting bar to attach the HTS seat to the toilet. The easy on-and-off feature allows caregivers to quickly position or remove the seat.
*Large HTS will always use round-front mounting bar for both elongated and round-front toilets.
