In <br /> this condition, handrails with a perimeter greater than 6-1/4 inches are required to provide <br /> a graspable finger recess area on both sides of the profile. The Stair Manufacturers <br /> Association funded a study that determined that a pinch grip could provide graspable <br /> handrail. This was added to the Residential Code in 2001 and the Building Code for <br /> multifamily residential in 2009. <br /> PRIMARY SECTIONS <br /> WA BC 1014.3.2 Type II ('21) WA RC R311.7.8.5 Grip Size ('21) <br /> I <br /> RELATED SECTIONS <br /> .
