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 /> . _ .. -- . ..n_n-a__i._I—--r__a J_:rn4-1__...fli n—p 2'4_2i_i_.-_4 iio.21— <br /> R315 Carbon Monoxide Alarms <br /> n <br /> R316 Foam Plastic n <br /> R317 Protection of Wood and Wood- "'" <br /> •. -• ' •• . i•. • D- . <br />
