Part Number System
Part Numbers assigned to TFL, THO, IHFL, IHF, THFI and
THF I-Joist hangers reveal the I-Joist sizes to be used
with the specic hanger. This guide will teach you how
to recognize I-Joist dimensions in the part numbers.
1st, 3rd, and sometimes 4th digits are whole numbers
(This example denotes 2 and 11)
4th digit may be part of a decimal –
TFL 23118
2nd and 5th digits are decimals
(see guide below)
(This example denotes .3125
[5/16] and .875 [7/8])
5th digit may be (0) or dropped if height is even
THO 35 925 -2
Part Number Guide for Decimals
1 = .125 or 1/8 inch
2 or 25 = .25 or 1/4 inch
3 = .3125 or 5/16 inch
5 = .5 or 1/2 inch
6 = .625 or 5/8 inch
7 = .75 or 3/4 inch
8 = .875 or 7/8 inch
THO 3 5 925 -2

Some Examples:
THO15950 .............. 1-1/2" x 9-1/2"
IHFL17925 ............... 1-3/4" x 9-1/4"
THO16925-2 ........... double 1-5/8" x 9-1/4"
THF23925-2............ double 2-5/16" x 9-1/4""
Note: MiTek’s USP Product Catalog lists a range of heights for IHFL/IHF
hangers. Face mount hangers can usually accommodate more than one I-Joist
height. The hanger height must be tall enough to support the top chord of the
I-Joist to eliminate web stiffener requirements for lateral stability. The IHFL/IHF
hanger must be a minimum of 60% of the joist height.
