Quick Product Summary

Best For

• Replacing a damaged, missing, or worn floating skimmer weir
• American Products-style skimmer applications calling for B-38
• Cross-reference replacement for R38013B or 850012
• Older skimmer installations where dimensional verification is important

Why This Matters

• A properly moving weir is part of normal surface-skimming operation.
• Exact cross-reference information helps reduce wrong-part orders.
• Matching the dimensions is especially useful on older skimmers with similar-looking replacement parts.
• Replacing only the worn weir can restore the intended skimmer component without replacing the complete skimmer body.

Common Signs You Need This / Use This When

• The existing floating weir is cracked, broken, missing, or no longer moving freely.
• Your current part is marked or cross-referenced as R38013B, 850012, or B-38.
• Your skimmer application requires a weir matching the listed CMP dimensions.
• The original weir no longer sits correctly in the skimmer opening.

Compatibility / Fitment Notes

CMP identifies 27180-038-000 as an American Products-style floating weir and cross-references it to R38013B, 850012, and B-38. Confirm the existing part number and compare the listed dimensions before ordering. Do not rely on appearance alone because older skimmer assemblies can use similar-looking baskets, doors, and weirs.

Installation / Use Notes

Use this replacement only in a skimmer application that matches the part number, cross-reference, and dimensions. Turn the circulation system off before servicing the skimmer, remove the existing weir as required by the skimmer design, and install the replacement in the same operating position. After reassembly, confirm the weir moves freely and follow the skimmer manufacturer's service instructions.
