THA/THAC Adjustable Truss Hangers
for Plated Truss


The THA series have extra long straps that can be field-formed to give height adjustability and top flange hanger convenience. THA hangers can be installed as top flange or face mount hangers.

THA4x and THA2x-2 models feature a dense nail pattern in the straps, which provides more installation options and allows for easy top flange installation.

Material: See table.

Finish: Galvanized, some products available in ZMAX® coating. See Corrosion Information.

Table
  1. Uplift has been increased 60% for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
  2. Wind (160) is a download rating.
  3. For single 4x2 top chord carrying members or single 2x nailers, the following THA hangers can be installed using 10dx1 1/2" top nails and 2-16d face nails with reduced allowable loads as noted: THA418/THA422: 1415 lbs. for DF/SP, 1215 lbs. for SPF; THA426: 2245 lbs. for DF/SP, 1930 lbs. for SPF; THA422-2/THA426-2: 2345 lbs. for DF/SP, 2015 lbs. for SPF. Loads are based on hanger installations at panel points.
  4. Face mount installation loads are based on minimum of 2-ply 2x carrying member. For single 2x carrying members, use 10dx1 1/2" nails into the carrying member and tabulated fasteners into the carried member, and use 0.80 of the table value for 18 gauge, and 0.68 of the table value for 16 gauge and 14 gauge.
  5. Min. Top Flange refers to the minimum length of strap that must be field formed over the header.
  6. For the THA 2x models, one strap may be installed vertically according to the face mount nailing requirements and the other strap wrapped over the truss chord according to the top flange nailing requirements (see drawing above) and achieve full tabulated top flange installation downloads.
  7. NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long. 10dx1 1/2" = 0.148" dia. x 1 1/2" long.
