Domus GTA-141 - 50mm Post Top Adaptor

The Domus GTA-141 is a post top adaptor — the collar that lets a Domus post-top lantern sit on a 50 mm column. Five powder-coated colours.

⭐ The middle of three sizes

• ⭐ 50 mm is the most common of the three on general-purpose steel and aluminium columns, so this is the one most retrofits need.
• ⚠ Measure the OUTSIDE diameter, not the inside and not the nominal pipe size — ⭐ a “50 mm” pipe is often 48 mm or 60 mm on the outside, which is precisely the mistake this part exists to prevent.
• ⚠ If your column is not 43, 50 or 60 mm, none of these will fit and no other adaptor is offered.

⛔ The title is the entire specification

• ⛔ This listing records one field: the warranty. No diameter, no height, no dimensions of any kind.
• ⚠ So the 50 mm exists only in the title, and everything else about the part — how tall the collar is, how wide the visible skirt is, how it fixes — is unrecorded.
• ⭐ Its 43 mm sibling at least records a diameter (165 mm, though unlabelled). ⭐ If the two share a body, 165 mm is the likely skirt here too — ⚠ but that is an inference from one listing to another, not a specification.
• ⭐ 9 of the 16 Domus GTA accessory listings are in this condition, recording a single field. ⭐ Ask us for anything you need to know — on parts this small the questions are short and the answers definite.

⭐ Why an adaptor matters at all

• ⭐ Post-top spigots are not standardised. A lantern made for one column will not sit on another, and there is no adjustment in the lantern itself.
• ⭐ So this small part is what makes a retrofit possible — putting a new lantern on a sound existing column instead of digging out a footing and replacing the whole post.
• ⚠ Nothing in the catalogue connects the adaptors to the lanterns. The post-top listings record no spigot size; these record no lantern. ⭐ Tell us both and we will match them.

⭐ Order it in the lantern's colour, at the same time

Five powder-coated finishes, the same palette as the lanterns. ⭐ The finish is applied to order, so a separate order is a separate batch — ⚠ and a collar sits directly beneath the lantern, where a mismatch shows.

Where it works

• Fitting a Domus post-top lantern to a 50 mm column.
• Retrofitting a sound existing post whose lantern has failed.
• A specified or heritage column.
• ⚠ Not without measuring the outside diameter first.
