Introduction
These roller tables provide infeed/outfeed support
for processing long workpieces on machines with
a working height of 24"– 40". They can be used
alone or connected together with optional con-
nector plates (T28371) to establish custom-length
roller supports for nearly any type of workflow.
Depending on the type of operation, the roller
tables can be set up next to machine as a stand-
alone unit, or they can be secured directly to
the machine with an optional mounting plate
(T28378).

Inventory To assemble roller table:
1. With help from an assistant, place roller table
assembly upside-down on cardboard or blan-
ket with wider lip of side rails facing up.
2. Secure each leg assembly to roller table
assembly with (4) M8-1.25 x 16 hex bolts, (4)
M8-1.25 hex nuts, and (4) 8mm flat washers
per leg (see Figure 5).
Note: If using T28378 Mounting Plate, install
on machine-mounting side of table before
securing leg assembly during Step 2.

The dynamic forces involved with process-
ing large/heavy workpieces may cause
unsecured roller tables to shift during cut-
ting operations, which could result in kick-
back injuries, depending on the type of
machine being used. To reduce this risk,
properly secure roller tables to both infeed
and outfeed side of your machine.
Assembly
It is easiest to assemble the roller table upside-
down, then have another person to help you turn
it upright when complete. If you are securing the
table to the machine, you will need to have the
optional T28378 Mounting Plate available at the
time of assembly.

To install roller table and adjust height:
1. Measure table height of machine that will be
used with roller table assembly.
2. With help from an assistant, place roller table
assembly upside-down on clean, level sur-
face (see Figure 6).
Installation & Height Adjustment
5. With help from an assistant, turn roller table
assembly rightside-up and position it next to
machine work table.
6. Adjust feet up/down as necessary to set
entire length of roller table even with machine
work table, then tighten hex nuts on feet to
secure in position (see Figure 8).
Roller table height adjusts from 24" to 40" with
adjustable legs and feet. The roller table must be
set to the same height as the machine work table.
The roller table should also be secured direct-
ly to the machine (using the optional T28378
Mounting Plate) to prevent it from shifting over
time. Depending on your setup and the type of
machine being used, a shifted roller table could
result in loss of cutting accuracy or kickback
injuries.
4. At each leg, loosen (4) cap screws securing
inner leg in sleeve, adjust leg in/out so height
of foot-to-ground matches measured height
of machine table, then secure cap screws
(see Figure 7).
Figure 6. Turn roller table over to adjust leg
height (T28369 shown).
Figure 8. Tighten (4) hex nuts on feet after
adjusting height (T28369 shown).

3. Loosen hex nuts securing feet and adjust
feet to middle of threaded shaft. This will
allow you to make fine adjustments up or
down later when finalizing roller table height
(see Figure 7).
7. If required for your setup, secure roller table
assembly to machine (refer to Securing
Roller Table to Machinery instructions later
in this document).

Connecting Multiple Roller Tables
To create a longer work support surface, any com-
bination of the T28172, T28369, and T28370 roller
tables can be connected end-to-end by using the
T28371 Connector Plates.
Items Needed Qty
Additional Person .............................................. 1
Wrench or Socket 18mm ................................... 1
Hex Wrench 6mm .............................................. 1
T28371 Connector Plates .................................. 2
To connect two roller table units end-to-end:
1. With help from an assistant, place two roller
table assemblies end to end, as shown in
Figure 9.
2. Adjsut table heights even with each other.
Refer to Installation & Height Adjustment
if necessary.
3. Working on one side at a time, remove the
(2) flange nuts securing adjoining end roller
shafts (see Figure 10).
4. Repeat Steps 2–3 on opposite side of tables
to attach second T28371 connector plate
(see Figure 11).
5. Check and adjust roller table to assure they
are even with each other across length of the
tables.

connect T28371 Connector Plate.

3. Install T28371 Connector Plate over thread-
ed end of roller shafts with lips facing out
(see Figure 11). Re-attach flange nuts and
tighten.

To secure roller table to machinery:
1. With help from an assistant, place roller table
assembly upside-down on clean, level sur-
face (see Figure 12).
2. Adjust leg height if necessary (see Installation
& Height Adjustment, Steps 1–6).
3. Remove (4) hex bolts, (4) flange nuts, and
(4) flat washers securing one leg assembly to
roller table assembly (see Figure 12).
Securing Roller Table to Machinery
8. Secure roller table with T28378 Mounting
Plate to machine using appropriate length
5⁄16" or 8mm hex bolts, hex nuts, and washers
as needed.
Note: If machine does not have existing
mounting holes, you will need to drill them
yourself.
7. Align roller table fitted with T28378 against
suitable machine.
To avoid machine damage and possible
electrocution/shock hazard, inspect work-
bench or machine to avoid drilling into wir-
ing or important internal components.
4. Insert T28378 Mounting Plate between leg
assembly and roller table assembly, and re-
install hex bolts, flange nuts, and flat washers
removed in Step 2. Finger-tighten for now.
5. With help from an assistant, turn roller table
assembly rightside-up.
6. Adjust location of T28378 Mounting Plate
if necessary, then secure (4) hex bolts,
(4) flange nuts, and (4) flat washers
re-installed in Step 4 (see Figure 13).
The dynamic forces involved with process-
ing large/heavy workpieces may cause
unsecured roller tables to shift during cut-
ting operations, which could result in kick-
back injuries, depending on the type of
machine being used. To reduce this risk,
properly secure roller tables to both infeed
and outfeed side of machine.
