Nixalite® Climbing Animal Barriers on Round Objects

These guidelines provide the basic steps for installing a climbing animal barrier on a vertical round pole. These steps are for a typical installation - your application may be different and may require different or additional steps. If you have any questions, Contact Nixalite.
For a hardcopy of these instructions download Climbing Barrier on Round Objects.

Installing on Round Objects:
NOTE: Do not use Blunt Tip Nixalite models for climbing animal barriers.

Where to start. Always begin the barrier installation at the top where the pole ends or where it meets the object it supports (example; a bird house, the ceiling, the bottom of a overhang).
Do You Have Enough Space? A typical six row climbing barrier takes up about 2-1/2 ft (76 cm). We recommend that the bottom row is at least 5 ft (152 cm) off the ground. You should have 7-1/2 ft (228 cm) of uninterrupted, vertical space to install the ideal climbing barrier. If not, Contact Nixalite for alternatives.
Accurately measure and record the diameter of the pole (the width of the pole).
If you know the circumference (distance around the outside) and need the diameter, divide the circumference by 3.14 (π).
firstlineround At the top of the pole, measure down 2-1/8 inches (5.4 cm) and draw a level line around the outside of the pole (the circumference).
nextlineround From the line just drawn, measure down 4-1/2 inches (11.4 cm) and draw another line around the outside of the pole. Repeat this step 4 more times until you have 6 individual lines spaced 4-1/2 inches (11.4 cm) apart.

Use the hardware spacing information below to find the quantity and spacing of mounting hardware needed for the pole diameter. To find the hardware that best suits your application, go to the Mounting Hardware page.
Mounting Hardware for Diameter Table
The quantity mounting hardware depends on the diameter of the pole.
Diameter  inches (cm)     Hardware
1-1/2” – 3" (3.8 – 7.6 cm)   3 units of hardware + 1 additional clip
3” – 5" (7.6 – 12.7 cm)   4 units of hardware + 1 additional clip
5" – 7” (12.7 – 17.8 cm)   5 units of hardware + 1 additional clip
7” – 9” (17.8 – 22.8 cm)   6 units of hardware + 1 additional clip
9” – 11” (22.8 – 28.0 cm)   7 units of hardware + 1 additional clip
11” – 13” (28.0 – 33.0 cm)   8 units of hardware + 1 additional clip
13” – 15” (33.0 – 38.1 cm)   9 units of hardware + 1 additional clip
1 mounting clip is added to the hardware totals for the double clip application.
1-1/2” diameter is the minimum diameter for this method.
15” is the maximum diameter for a single 4 foot strip.
doubleclipround At each line, mark the mounting hardware locations, spacing them equally around the outside of the pole. Install the clip with the hook end pointing towards the ground.NOTE: one hardware location will have 2 CLIPS to fasten both ends of the same Nixalite strip. That is the reason for the additional clip noted in the chart. Tip: to help prevent gaps, move the double clip location about 30 degrees from row to row (so it doesn't line up from one row to the next).

meetinmiddleround
Before installing the Nixalite strip, make sure it will go around the circumference of the pole, beginning and ending at the double clip hardware. Cut the Nixalite strip to fit (if needed) and pull the Nixalite base strip down into the hook of the mounting clips. Repeat for each row.
