3 THREADED SPLIE SYSTEM The Threaded Splice System is designed to eliminate protruding rebar problems. OSHA requirements pertaining to workmen protection from protruding rebar has become a source of added concern and expense. Use of the Threaded Splice System helps eliminate the exposed rebar problem. It offers complete workman safety, reduces costs related to injuries and reduces the need for expensive rebar protectors. The Threaded Splice System consists of a threaded rebar coupler and a threaded splice bar and complies with AI Type 1, that requires mechanical splices to develop 125% of the specified rebar yield strength. Refer to the Tables for coupler and bar data. Bar Size Designation ASTM A-615 GRADE 60 REINFOREMENT BAR DATA Weight (lbs per lineal ft.)

4 (5420) (5425) R-61, R-63 SETTING BAR ASSEMBLIES Setting Bars are assemblies comprised of threaded rebar coupler and a length of Grade 60 deformed reinforcing steel threaded on one end. Setting Bars are available in all rebar sizes #4 through #11 and in any required length. The Setting Bar (R-61) model is furnished straight for standard lap splice applications and the Setting Bar (R-63) is furnished with a 90 bend. All setting bars are manufactured to furnished job specifications. A 13 L A R-61 L R-63 B To Order, Specify: For Setting Bar (R-61) quantity, type, rebar size and overall length. ( A + L ) For Setting Bar (R-63) quantity, type, rebar size, A and B dimensions MB0612

5 (5430) (5435) (5440) (5445) R-61, R-62, R-63, R-64 SPLIE BARS R-61 R-62 The R-61, R-62, R-63 and R-64 Splice Bars are manufactured from Grade 60 deformed rebar material and are available in all of the corresponding sizes to the Threaded Rebar oupler. After the Setting Bar has been placed and the concrete has set the Splice Bar is threaded into the Setting Bar to complete the splice. Splice Bars are available in the following configurations: R-61 straight, R bend, R-62 threaded at both ends and with a R-64 return bend. 14 For Hook Bar development lengths actual dimensions, B, D and R are functions of f c (concrete strength), PSI and minimums based on AI section 12.5 both code and commentary.
