GTA-94-Post Top Thread Exterior Range

The Domus GTA-94 is a post-top thread adaptor for the traditional exterior range — aluminium, in five colours, made to order.

⭐ The part that makes a lantern and a post into a fitting

• ⭐⭐ A POST-TOP LANTERN AND A POST ARE TWO SEPARATE THINGS, AND SOMETHING HAS TO JOIN THEM. ⭐ This adaptor is the threaded connector that does it.
• ⭐ IT IS THE COMMONEST OMISSION ON AN OTHERWISE COMPLETE ORDER. ⭐ The lantern is specified, the post is specified, the cable is run — and the adaptor is discovered on installation day, when the two parts will not meet.
• ⭐ ON A MADE-TO-ORDER RANGE THAT IS A TEN-DAY STOP, not a trip to the wholesaler. ⚠ The post is standing, the cable is live, and the lantern is on the ground.
• ⭐ SO CONFIRM THE FULL PARTS LIST BEFORE ORDERING — ⭐ lantern, post, base, adaptor — and tell us the arrangement rather than the part numbers if you are unsure. We would rather check than have you wait.

⭐ "Traditional exterior range" spans several families — confirm the thread

• ⚠ “Traditional exterior range” is a range description rather than a part number. ⭐ It covers several families — TURIN, VIENNA, PARIS, CHESTER, AVIGNON, SIENA and others — which share a visual language but not necessarily every component.
• ⭐⭐ THE THREAD IS WHAT HAS TO MATCH, AND A THREAD IS NOT SOMETHING YOU CAN JUDGE FROM A PHOTOGRAPH. ⭐ Diameter, pitch and length all have to be right, and a nearly-right thread is worse than an obviously wrong one because it will start and then bind.
• ⭐ THE RELIABLE IDENTIFIERS ARE THE GT CODE ON THE ORIGINAL FITTING plus the outside diameter of the post at its top. ⭐ Measure and send us the figure with a photograph of the existing joint.
• ⚠ IF YOU ARE JOINING PARTS FROM TWO DIFFERENT FAMILIES, ASK FIRST. ⭐ It sometimes works and sometimes does not, and the answer is not deducible from the listings.

⭐ Five colours on a part that barely shows

⭐ Beige, black, burgundy, green and white, applied to order. ⭐⭐ THE ADAPTOR SITS AT THE JOINT BETWEEN LANTERN AND POST, SO IT IS MOSTLY HIDDEN — but a mismatched collar at that joint is exactly the sort of detail that reads as wrong. ⭐ Order it in the colour of the post and lantern it is joining, not the colour the range was originally specified in; on a property lit ten years ago those may differ. ⚠ And expect a new adaptor to be brighter than the weathered parts either side of it. ⭐ At a joint that is usually acceptable, and it is one of the few places on an exterior fitting where a slight mismatch genuinely does not matter.

⭐ What this part does not have, and why that is right

• ⭐ No voltage, no wattage, no IP rating, no lamp base. ⭐⭐ AN ADAPTOR IS STRUCTURAL, NOT ELECTRICAL — the cable passes through it, but the adaptor itself has no electrical parts.
• ⭐ IT CORRECTLY PUBLISHES ONLY A WARRANTY. ⚠ That is unusual in this catalogue: 83 of 104 passive parts carry an electrical field they cannot have.
• ⚠ WHAT IS GENUINELY MISSING IS THE THREAD SPECIFICATION. ⭐ For a connector, the thread is the whole product — and it is not published. ⭐ Ask us and we will confirm with Domus before you order.
• ⭐ THE SAME APPLIES TO ITS DIMENSIONS — ⭐ a length and an outside diameter would let a buyer check compatibility without asking, and neither is listed.

⚠ Cable continuity through the joint

⭐ The supply cable runs from the post, through the adaptor, into the lantern. ⭐⭐ LEAVE ENOUGH SLACK AT THE JOINT TO MAKE THE CONNECTION COMFORTABLY, and dress the cable so it is not pinched as the adaptor is threaded home — ⭐ a cable trapped in a thread is a fault that appears months later, when vibration has worn through the insulation. ⭐ Check the cable entry is protected against the aluminium edge, and that any grommet is seated before final assembly. ⚠ This is an electrician's job.

⛔ Made to order

Allow up to 10 business days for production. ⚠ Which is exactly why it should be ordered with the fitting rather than after it.

✅ What is published

Where it works

• ⭐⭐ Ordered WITH the lantern and post — ⭐ not after.
• ⭐ Replacing a corroded joint — ⭐ keeping post and lantern.
• ⭐ Where the post outside diameter is known.
• ⛔ Not ordered on the range name alone — ⭐ confirm the thread.
• ⚠ Not across two families without asking first.

Specifying it

Post-top thread adaptor to suit the traditional exterior range. Aluminium, five colours applied to order. No electrical parts. Made to order, up to 10 business days. 1-year warranty. ⭐ THIS IS THE PART THAT MAKES A LANTERN AND A POST INTO A FITTING, AND IT IS THE COMMONEST OMISSION ON AN OTHERWISE COMPLETE ORDER. The lantern is specified, the post is specified, the cable is run — and the adaptor is discovered on installation day, when the two parts will not meet. On a made-to-order range that is a ten-day stop with the post standing and the lantern on the ground. ⚠ "TRADITIONAL EXTERIOR RANGE" IS A RANGE DESCRIPTION RATHER THAN A PART NUMBER, and the thread is what has to match — diameter, pitch and length, none of which is judgeable from a photograph, and a nearly-right thread is worse than an obviously wrong one because it will start and then bind. ⚠ THE THREAD SPECIFICATION IS NOT PUBLISHED. Ask us.
