<br />LTT/HTT TellslOn TIes
<br />
<br />TensIon lies offer a solullon for resIsting tensIon loads that Is fastened with nails.
<br />The entire line of tension ties has been tested and evaluated to the reqUirements of
<br />AC155. .
<br />The HTT4 and HTT5 are the latest generallon 01 tension tIes. They feature an
<br />opllmlzed nailing pattern whIch results In better performance with less deflecllon.
<br />Designed to meet new code standards, the HTT4 and HTT5 offer higher loads than
<br />their predecessors.
<br />The LTT19 LIght Tension Tie Is designed for 2x lolsts or purllns and the LTT20B
<br />Is for nall- or bolt-on applications. The 3' nail spacing makes the LTT20B suitable for
<br />wood I'Jo]sts with 10dx1~. The LTTI31Is designed for wood chord open web truss
<br />attachments to concrete or masonry walls and may also be Installed vertically on a
<br />mInImum 2x6 stud.
<br />MATERIAL: See table
<br />FINISH: GalvanIzed. May be ordered HDG; contact SImpson Strong-Tie.
<br />INSTALLATION: . Use all spec/fled fasteners. See General Notes.
<br />. For use In vertical and horizontal appllcal1ons.
<br />. To tie multiple 2X members together, the
<br />Designer must determine the fasteners
<br />required to JoIn members without splitlfng
<br />the wood,
<br />. The Designer shall specify anchor bolt
<br />type, length and embedment. See SB and
<br />S8TB anchor bolts on pages 36-40.
<br />CODES: See page 20 for Code Reference Key Chart,
