Installation

  • Select appropriate STB or STBL Anchor Bolt.
  • Use normal weight concrete with minimum compressive strength of 2,500 psi.
  • Minimum center-to-center spacing between bolts is 3(E) for anchors acting simultaneously in tension.
  • Match embedment depth with embedment line on the STB or STBL shaft.
  • The STB or STBL does not need to be tied to the rebar.
  • Nuts and washers are not included.
  • Monolithic or Stem Wall Foundations – Prior to pour, install the STB or STBL in an upright position and at a 45° angle to the wall. Install one horizontal #4 rebar at a depth of 4″ minimum. See images fpr more details.
  • Concrete Block Applications – Prior to cell pour, install the STB or STBL in an upright position and at a 45° angle to the wall. (See illustrations.) Use the embossed angle guide on the end of the STB or STBL shaft as a guide. Install one horizontal #4 rebar at a depth of 4″ and one vertical #4 rebar maximum 48″ o.c. spacing. Fill all cells with concrete having a minimum 2,500 psi compressive strength.
