EBAA IRON 1703 MEGALUG Restraint Harness
Product Information
The Series 1700 is a pipe restraint system designed for restraining ductile iron pipes with push-on pipe bells. It is suitable for use on water or wastewater pipelines subject to hydrostatic pressure and tested in accordance with either AWWA C600 or ASTM D2774. The product is made in the USA by EBAA Iron.
The Series 1700 comes in various sizes, ranging from 3 inches to 54 inches in nominal pipe size. Each size is assigned a specific series number for identification. The product has approximate rated pressure (PSI) ratings ranging from 16.91 to 1,923.56 PSI, depending on the size.
Product Usage Instructions
- Install the split ring behind the bell in the direction indicated on the casting. Tighten the clamp bolts to 90 ft-lbs.
- Assemble the push-on joint per the pipe manufacturer’s instructions.
- Install the tie bolts in each available bolt hole for maximum distribution of operating forces. Place nuts on the end of the tie bolts, leaving several threads showing.
- Pull the restraint ring away from the joint until the slack is removed from the tie bolts.
- Tighten the torque limiting twist-off nuts in a clockwise direction (as indicated by the arrow on top of the nut) until all wedges are in firm contact with the pipe surface. Continue tightening in an alternate manner until all of the nuts have been twisted off.
- Tighten the tie bolt nuts until the ring behind the bell is in firm contact with the back of the bell. Do not overtighten these bolts to avoid forcing the spigot further into the bell.
- If removal is necessary, use the 1-inch hex heads provided. If reassembly is required, follow the same steps as indicated above and tighten the wedge bolts to 90 ft-lbs.
Note: For applications with pressure requirements other than those shown or for any assistance, please contact EBAA for support.

Sample Specification
Ductile iron pipe bell restraint shall consist of a wedge action restraint ring on the spigot joined to a split ductile iron ring behind the bell. The restraint ring shall have individually actuated wedges that increase their resistance to pull-out as pressure or external forces increase. The restraint ring and its wedging components shall be made of ductile iron conforming to ASTM A536. The wedges shall be heat treated to a minimum hardness of 370 BHN. Torque limiting twist off nuts shall be used to insure proper actuation of the restraining wedges. The split ring shall be made of ductile iron conforming to ASTM A536. The restraint devices shall be coated using MEGA-BOND®. (For complete specifications on MEGA-BOND visit www.ebaa.com.) The connecting tie rods that join the two rings shall be made of low alloy steel that conforms to ANSI/AWWA C111/A21.11. Side clamp bolts shall be of SAE J429 Grade 5 material. The assembly shall have a rated pressure with a minimum two to one safety factor of 350 PSI in the sixteen inch size and below 250 PSI in the eighteen through thirty-six inch sizes. The product shall be the Series 1700 MEGALUG® restraint harness, manufactured by EBAA Iron, Inc., or approved equal.

Installation Instructions
- The Series 1700 is designed for restraining ductile iron pipe, conforming to ANSI/AWWA C151/A21.51 (all thickness classes) push-on pipe bells. It has a restraint ring on the spigot and a split ring behind the bell.
- Install the split ring behind the bell in the direction indicated on the casting. Tighten the clamp bolts to 90 ft-lbs.
- Place the Series 1100 MEGALUG® restraint gland on the spigot with the lip extension toward the bell.
- Assemble the push-on joint per the pipe manufacturer’s instructions.
- Position the Series 1100 MEGALUG® restraint on the spigot such that the bolts are in alignment and the distance between the rings is suitable for the tie bolt length. Allow enough room on the tie bolt to fully engage the nuts with several threads showing.
- Install the tie bolts in each available bolt hole for maximum distribution of operating forces. Place nuts on the end of the tie bolts. Allow room on the tie bolt to fully engage the nut with several threads showing.
- Pull the restraint ring away from the joint until the slack is removed from the tie bolts.
- Tighten the torque limiting twist-off nuts in a clockwise direction (direction indicated by arrow on top of nut) until all wedges are in firm contact with the pipe surface. Continue tightening in an alternate manner until all of the nuts have been twisted off.
- Tighten the tie bolt nuts until the ring behind the bell is in firm contact with the back of the bell. Do not tighten these bolts enough to force the spigot further into the bell.
- If removal is necessary; use the ⅝ inch hex heads provided. If reassembly is required, assemble the product in the same manner as indicated in the previous steps and tighten the wedge bolts to 90 ft-lbs.
Series 1742 through 1754 are comprised of two MEGALUGS ; one on the spigot and
the other behind the bell.
NOTES: Dimension are in inches and are subject to change without notice.
