All Ranger II’s require more than one segment to complete a spacer. In addition, all Ranger II’s are available with a number of different runner height options which are used to guarantee clearance of the mechanical joint, provide for options in carrier pipe positioning within the casing or to compensate for grade elevation adjustments. Following are examples on how to size Ranger II spacers for various applications. Example 1 Installation with Equal Length Runners - Maximum Allowable Height 20” Ductile Iron pipe (21.60” O.D. barrel & 28.63” O.D. bell) inside a 36” casing with a 0.375” wall thickness. A. Find carrier pipe O.D. (21.60”) from chart and choose the proper size and number of segments. One spacer would require 5 - Maxi segments. B. Determine maximum runner height with equal length runners. Casing I.D. 35.25” Less Carrier Pipe O.D. -21.60” 13.65" Less Space Allowance -1.00” 12.65" Divide this number (12.65”) by 2 to obtain the total allowable runner height = 6.325” C. Choose a runner height of this value or less. Solution: 5 - Maxi segments with runner heights of 5.91”. Note: This combination will also restrain the pipe from flotation within the casing pipe by allowing only about 1.8” of clearance between the top runners and the casing I.D. Example 2 - Carrier Pipe Installed Just To Clear the Bell. Suggested minimum clearance is at least 1” (1/2” on both sides) 20” Ductile Iron pipe (21.60” O.D. barrel & 28.63” O.D. bell) inside a 36” casing with a 0.375” wall thickness. A. Find carrier pipe O.D. from chart (21.60”) and choose the proper size and number of segments. One spacer would require 5 - Maxi segments. B. Determine runner height. Bell O.D. 28.63” Add 1” Clearance +1.00” 29.63” Less Barrel O.D. -21.60” 8.03” Divide this number (8.03”) by 2 to obtain the minimum runner height to just clear the bell = 4.01” C. Choose a runner height between 4.01” and the maximum allowable runner height (6.32”) determined in Example 1. Solution: 5 - Maxi segments with runner heights of 4.92”. Example 3 - Carrier Pipe Centered in Casing (within approximately 1/2” of casing center) 20” Ductile Iron pipe (21.60” O.D. barrel & 28.63” O.D. bell) inside a 36” casing with a 0.375” wall thickness. A. Find carrier pipe O.D. from chart (21.60”) and choose the proper size and number of segments. One spacer would require 5 - Maxi segments. B. Determine runner height. Casing I.D. (35.25”) divided by 2 17.625” Less Carrier Barrel O.D. (21.60”) divided by 2 -10.80” 6.82” Choose a runner height closest to this value (6.82”). On the chart a 6.89” runner would be closest, however 6.88” is larger than the maximum allowable runner height as determined in Example 1. In this case, use 6.88” runners on the bottom to center the carrier pipe approximately and adjust the top runner heights to allow insertion within the casing. Use the following procedure to determine max. height for top runners: Casing I.D. 35.25” Less Space Allowance -1.00” Less Carrier Pipe Barrel O.D. -21.60” Less Bottom Runner Height -6.88” Desirable Top Runner Height 5.77” Select the closest runner height from the chart less than (5.77”). In this case a 4.92” runner height would be specified for the top runners. Also verify this is of sufficient height to clear the bell (4.01”) which in this case it is. Solution: 2 - Maxi segments with runner heights of 6.89” and 3 Maxi segments with runner heights of 4.92”. Example 4 - Ranger II used to Adjust for Grade Elevation Changes Within a “segment size” various height runners may be used to adjust for grade elevations. In the above example a 20” Ductile Iron pipe with a 21.60” O.D. will require 5 Maxi segments to make a complete casing spacer. One could use any combination of Maxi segments with runners between the Minimum Allowable Runner Height of 4.01” and the Maximum Allowable Runner Height of 6.32” to position the carrier pipe at a particular height. Any other combination of runner heights of Maxi segments that fall between these values may be used, although no more than half of the segments should consist of the higher runner height segments. Please contact PSI if you are uncertain of the fit for a particular application.

Basic Installation Procedure PRECAUTIONS Always Use Appropriate Protective Safety Wear and Glasses! 1. Always wear protective safety glasses, especially in low temperatures. 2. Keep Ranger II segments and slide-locks in a warm environment while awaiting installation in colder climates. 3. Under hot installation conditions, allow the product to age a couple of hours at ambient temperature prior to assembly. 1. Check to make sure you have all segments and Slide-Locks as recommended by ordering procedure. 2. Take the segments and align the buckles. Insert the buckles 1/4 of the way into the slots. 3. Locate directional arrow on segment and insert Slide-Lock until the tip exits the end of the segment. 4. Continue the process from the previous step until all segments are put together. You are now ready to wrap the Ranger II around the pipe. NOTE: In tight installation areas, you might need to break the belt into two parts and then wrap the Ranger II around the pipe. 5. Align the buckles and lock into place. Take the final Slide-Lock and slide completely into place. 6. Insert all Slide-Locks as far as possible by hand. Complete tightening by lightly tapping each Slide-Lock with a light rubber headed hammer, while holding the Slide-Lock against the pipe. 7A. To tighten Ranger II securely to carrier pipe, back Slide-Lock completely out of the slot. If needed, push segments together by hand. 7B. Re-insert Slide-Locks completely into segment by lightly tapping Slide-Lock back into position while holding the Slide-Lock against pipe. 7. Continue steps 7A and 7B until Ranger II is secure against carrier pipe and unable to move. Trouble Shooting Installation Procedure Broken Slide Lock: A) If a Slide-Lock should break during installation, remove and replace with a new Slide-Lock. B) Remove Slide-Lock by backing it out, do not pull it through to remove the broken piece. Tap broken piece back out. C) Take a Slide-Lock and insert in the opposite direction of the arrows. Push until you can grab the broken piece and remove. Slide Lock will not insert completely: D) If the Slide-Lock does not completely lock into place the following may have occurred. Two or more segments may have engaged completely. To rectify, back Slide-Lock out and readjust segments by pulling them apart by hand. Reinsert Slide-Lock and adjust tightness of the spacer with another segment.
