Sea-Dog 290901-1
Conventional 90-degree universal tee. Check for a one-piece rail connection; it is not the hinged version.
Identify Sea-Dog 290901 vs 290904 1-Inch Stainless Handrail Tees
Sea-Dog 290901-1 and 290904-1 both connect 1-inch outside-diameter marine rail at a right angle, but the joining styles differ. The universal model is a conventional tee, while the hinged tee can open around an existing tube. Use this reference to identify the correct fitting before replacing a rail component.

Manufacturer part-number reference
| Part number | Style | Tube OD | Material | Assembly |
|---|---|---|---|---|
| 290901-1 | 90° universal tee | 1 inch | 316 stainless steel | Conventional |
| 290904-1 | 90° hinged tee | 1 inch | 316 stainless steel | Hinged |
Sea-Dog specifies a 0.049-inch stainless tube wall reference. The manufacturer's handrail tee range includes set screws where appropriate; replacements are identified as 299999-1. A 1/8-inch Allen wrench is specified for installation. Match the original rail design before ordering.
What to check on the original rail
- Check whether the existing tee is hinged or conventional.
- Measure tube outside diameter: these two specific MPNs are for 1 inch, not 7/8 inch.
- Confirm the 90-degree connection and space available to fit the replacement.
- Review actual condition, mounting hardware and included set screws in the listing.
