Ramset 800-20-51 Limit Nut 1-Inch ID

Mechanical Open and Close Limit Adjustment for Ramset Gate Operators

The Ramset 800-20-51 is a replacement limit nut used in the mechanical limit assembly of compatible Ramset gate operators, including the RAM 1000 and RAM 5500S. Mounted on the threaded limit shaft, the nut is positioned to determine where the operator reaches its open or close stopping point.

Ramset uses separate left and right limit nuts to control the two ends of gate travel. During adjustment, the appropriate limit nut is released and moved along the threaded shaft until the gate stops at the desired position. This allows an installer or service technician to fine-tune gate travel without repositioning the entire limit assembly.

A worn, damaged, or difficult-to-adjust limit nut can interfere with proper limit setup and make it harder to maintain the intended gate opening or closing position. The Ramset 800-20-51 has a 1-inch inside diameter and is intended as a replacement where this specific part number is required.

Conclusion

The Ramset 800-20-51 is used to replace a limit nut in compatible RAM 1000 and RAM 5500S gate operators when the existing component is worn, damaged, or no longer adjusts properly. Because the operator uses separate limit nuts for the two ends of travel, confirm which nut requires replacement and verify part number 800-20-51 before ordering.
