Description
The Ranger II is an all non-metallic casing isolator/spacer system that uses molded segments to encircle the carrier pipe. Each segment includes at least one molded-in runner and one slide lock. Customer's may choose from any one of five different size bands to allow correct sizing for carrier pipe O.D. ranges from 0.83" (21.1mm) up to 37.60" (95.5cm) in diameter.
Once sized, the segments are placed around the carrier pipe and cinched together via non-metallic slide locks. Installation is quick and easy while only a small inventory of segments may be used to accommodate a large variety of pipe styles, types and diameters.
Targeted Use - Water
For carrier pipe diameters ranging from 0.83” (21mm) to 37.60” (955mm).
For carrier pipe insertion lengths up to 400 feet.* (121.9M)
Spacing Recommendation: Max 8’ ( 243.8cm) between spacers, Max 2’ (61.0cm) from casing pipe end, Max 2’ (61.0cm) on each side of bell or mechanical joint.
Recommended End Seals: Model C, S, W, and R.
Ranger II spacers should not be used on concrete carrier pipe. Engineered equal to 304 Stainless Steel Metallic Casing Spacers. Excellent for the Stocking Distributor.

Separate segments are connectedby inserting the buckles into slots on the adjacent segment. Slot accepts Slide- Lock. Arrow molded on segment indicates correct insertion direction.
Slide-Lock is used to tension the segments together after installation on pipe. Channels face up during insertion while the correct size Slide-Lock (micro, mini, midi, medi, maxi) is molded on the flat (bottom) side.

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. |

Size your Installation Application
All Ranger II. Casing Spacers require more than one segment to complete a spacer. In addition, all Ranger II Casing Spacers 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 Casing Spacers for various applications. Detailed Ranger II casing spacers weight & spacing guidelines on page 11. For exact centering and adjusting for grade elevation changes contact PSI.
Examples
Centered & Restrained with Equal Length Runners
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 adjacent chart and choose the proper size and number of segments. One spacer would require 5 - Medi segments.
B. Determine maximum runner height with equal length runners.
Case 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 maximum runner height = 6.325”
C. Choose a runner height of this value or less.
Solution: Use 5 - Medi (150) segments with runner heights of 5.91”.
Note: This combination will 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. This will center the carrier pipe within approximately 0.9” of exact center.
To Clear the Bell (suggested minimum clearance is at least 0.8” (0.4” 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.
Determine runner height.
(Clear Bell)
Bell O.D. | 28.63" |
Add 0.8" Clearance | +0.80" 29.43" |
Less Barrel O.D. | -21.60" 7.83" |
Divide this number (7.83”) by 2 to obtain the minimum runner height to clear the bell = 3.92”
Choose a runner height between 3.92” and the maximum allowable runner height (6.32”) determined in the above example.
Solution: Use 5 - Medi (100) segments with runner heights of 3.94”.
