  (CS) CONTINUOUS SUPPORT (ZIG-ZAG)
  CS Continuous Support (Zig-Zag) is a steel support for horizontal wire mesh,
  structural fabric or reinforcing bars and an excellent spacer for vertical steel in concrete
  walls. The support is very stable, it will not slide or tip and has excellent load carrying
  capacity. It is easy to install and can be bent around voids and/or partitions.

  WIRE GIRDER – DOUBLE
  The Wire Girder – Double is designed to quickly and accurately position wire mesh in large slab-
  on-grade applications. The girder is available in heights from 3” to 9” in 1” increments and in
  lengths up to 40’. Optional snap-on sand plates are available for use on sandy soils to prevent
  the girder from turning during concrete placement. When using on a firm casting bed, the snap-
  on plates are not a necessity but will give better support on slabs exceeding 6” in thickness.

  The optional snap-on plates are field installed by simply squeezing the bottom runners of the girder
  inward until they slip inside the plate tabs. Release of the runners will let them slide under the tabs
  and be held firmly in place by the tabs.

  To Order Specify: quantity, type, height & length.
  To Order Optional Snap-On Plate, Specify: quantity and type.

 TUFF PLUS SB – SLAB BOLSTER
 The Tuff Plus SB is a composite slab bolster that is used to provide accurate cover for lower mats
 of steel reinforcement in concrete elements. Suitable for a wide range of uses, the Tuff Plus SBslab
 bolster can be used in Tilt-Up Concrete Construction, Precast Concrete Construction, Post
 Tensioned Concrete and other Cast in place applications. The Tuff Plus SB, all plastic slab bolster,
 may also be used as side form spacers in vertical formwork.

 The Tuff Plus SB slab bolster is fabricated from fiber filled gray composite material designed to
 blend with the concrete surface, if exposed. Top bar corrugations are placed on 1” centers to
 visually aid rebar placement. The Tuff Plus SB plastic slab bolster is manufactured in true 60”
 lengths, eliminating assembly and expedites field placement.

   BT Couplers
   Type 1 & Type 2HS Rebar Splicing System

   BT Couplers are a versatile and robust mechanical rebar splicing system.
   BT Couplers are a Type 1 & Type 2HS Rebar Splicing System used to
   mechanically connect rebar sections in segmental pours as an alternative
   to traditional dowel bars. The three-part system consists of a Splice
   Bar, Coupler and Setting Bar that meets the mechanical splice strength
   requirements of ACI-318-19 when used to splice grade 60 rebar.

   FEATURES
   • Improved performance: Exceeds ACI-318-19 Type 1 & Type 2HS splice
     requirements and maintains reinforcing steel continuity independent of
     concrete cover.
   • Saves time and money: Reduces costly form repairs by eliminating drilling
     of forms and simplifies form striping.
   • Available in standardized lengths (sizes #4 – #11) and configured to order.

 SETTING BAR ASSEMBLIES

 Meadow Burke BT 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 (RC-61/RC-61T2) model is furnished
 straight for standard lap splice applications and the Setting Bar (RC-63/RC-63T2) is furnished with a 90° bend. All setting bars are manufactured to
 furnished job specifications.

 Meadow Burke BT Splice Bars are manufactured from Grade 60 deformed rebar material and are available in all of the corresponding sizes to the
 Threaded Rebar Coupler. 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: RC-61/RC-61T2 straight, RC-63/RC-63T2 90° bend, RC-62/RC-62T2 threaded at both
 ends and with a RC-64/RC-64T2 return bend.

 For Hook Bar development lengths actual dimensions C, B, D and R are functions of f’c (concrete strength), PSI and minimums based on ACI-318-05
 section 12.5 both code and commentary.

 ZAP SCREWLOCK®
 DOUBLE ZAP SCREWLOCK®
 The ZAP Screwlock® is a high strength mechanical rebar connection device available for splicing #4 through #11 rebar. No rebar end
 preparation is required. Simply insert the ends of the two bars into the connector body. A positive center stop ensures proper installation.

 Tightening the lock-bolts generates a positive mechanical interlock as the rebar deformations are pressed into the ductile steel wedge-shaped
 body of the connector. Visual inspection is easily accomplished; just verify that the heads of the lock-bolts have sheared off during the
 tightening sequence.

 The ZAP SCREWLOCK exceeds 125% of the specified yield strength of the rebar and is approved by or meets the following: ACI-318, ICBO
 and AASHTO.
