of smaller holes for electrical and 
technology lines. Hole sizes range 
from 4-1/4" oval to 10" round, based 
on member depth.
They oer consistent quality, 
predictable performance and high 
strength-to-weight ratio.

TradeReady R I M 
Another major component of the 
TradeReady floor system, the 
standard 16'-long rim drastically 
reduces framing time and eort. 
Rims have pre-formed, prepunched 
attachment tabs at 12", 16", 19.2" 
or 24" o.c. spacing to eliminate 
layout time—and ensure fast, 
proper fastener placement. 
Embossed stiening ribs on each 
side of the tabs provide additional 
reinforcement, for a significant 
reduction of web stieners (squash 
blocks) and support clips in a 
majority of applications.
