Launched at World of Concrete 2018, the battery operated TwinTier RB441T is faster and delivers greater efficiency and labor savings than the company’s earlier rebar tying tools. Product engineers cite among leading TwinTier attributes: faster tying speed, which further increases productivity; a reduction in wire consumption, adding to cost savings for end users; and, a wire tie that is shorter in height, thereby requiring less concrete cover.

| One coil of (from left) steel, poly coated or electro-galvanized wire yields nearly 250 ties, based on a uniform #4 bar sizing. |
The tool simultaneously shoots two 19-gauge wires around rebar intersections, wrapping once to form a tie equivalent to the strength of a hand snap tie. It uses TW1061T wire, available in steel, poly coated or electrogalvanized options and equal to 240 ties per coil with #4 x #4 bar. A 4.0-amp lithium ion battery will complete up to 4,000 ties before any need to recharge.
A large jaw allows TwinTier users to tie #3 x #3 up to #7 x #7 rebar, while a new enclosed design offers greater protection against debris and moisture. Like companion Max rebar tying tools, the TwinTier RB441T’s simple operation helps reduce muscular skeletal injuries when compared to hand tying. Reports from NIOSH (HEATA #2003-0146-2976) and Canadian Safety Association of Ontario (WSIB Grant #01023) support the injury-reduction case for tool-based versus manual rebar tying. — Max USA Corp., Mineola, N.Y., 800/223-4293; www.maxusacorp.com
