Pulling Procedures . . .
1. The pulling line should be connected to the tube
bundle using an appropriate sized Kellems grip for your
application. Do not use a damaged grip for pulling bundle.
Pulling tension should not exceed 22.7kg, with a minimum
pulling line of 15mm.

2. Position tubing bundle reel at the top or base of the stack
in line with cable tray to reduce overall friction on pulling
run. Pulling should allow someone at the end to stop the
reel from turning when the pulling force is stopped.
3. Extreme pulling tension may tend to fl atten the tubes and
damage heat tracing as they round corners, etc. Observe
the minimum bending radius of the tubing bundle during
pulling operation. (Refer to Table 1 Bend Radius)
4. For rounding corners, a pulley or roller may be utilized
while passing over sharp edges that might damage the
bundle. Both the pulleys and rollers can be rented at many
electrical supply houses.
5. Kellems grips are required for permanently securing
the bundle to the stack every 10.67m. NOTE: Kellems
grips used for bundle installation will also be used to
permanently attach bundle to support structure.
6. After determining the total number of Kellems grips
required for permanent installation, slide grips required
over bundle as shown on Illustration D. Use duct tape
to prevent Kellems grips from slipping during bundle
installation.
7. Attach pull rope to the pulling eye in the Kellems grip.
Do not connect any type of hook, clamp or attachment
hardware to any other part of the grip.
8. Secure pulling rope to fi rst Kellems grip leaving suffi cient
line for additional grips as required. See pulling detail
illustration. Do not exceed spacing of 10.67m between
grips.
