The Domus GTA-832 is a post base complete with thread, to suitthe traditional exterior range aluminium, in five colours, madeto order.

This is the part that carries the load

• EVERYTHING ELSE IN A POST LIGHT IS SUPPORTED BY THIS. The column, thearms, the lanterns and their lamps all transfer their weight and their wind load through the base to thefooting.
• WHICH MAKES IT THE ONE COMPONENT WHOSE FAILURE TAKES THE WHOLE FITTING DOWN. A cracked diffuser is a repair; a failed base is a post lying across adriveway.
• THE THREAD IS THE WORKING PART. Complete with thread meansthe base arrives with the threaded connection the column screws into, rather than needing one fitted so it is a like-for-like replacement rather than a fabricationjob.
• REPLACING A BASE IS NOT A LANTERN SWAP. The post has to come down, whichmeans the cable disconnected at the base and the fitting supported while the new base is set. Treat it asan electrician-plus-labour job, not a householder one.

Why a base fails, and what to look for

• THE BASE SITS AT GROUND LEVEL, WHICH IS THE HARSHEST POSITION ON THE WHOLEFITTING.
  • WATER COLLECTS AGAINST IT rain runs down the column and stops atthe base, and mulch or soil banked against it holds that water incontact.
  • IRRIGATION AND FERTILISER REACH IT. Fertiliser salts are aggressive toaluminium and its coating, and a sprinkler aimed at a bed hits the basedaily.
  • MOWERS AND EDGERS HIT IT. Each strike is a chip, and a chip is wherecorrosion starts under the powder coat.
• SO INSPECT THE BOTTOM 300 mm, NOT THE LANTERN, when checking an ageingpost. Blistering or lifting paint at the base means corrosion is already runningunderneath.
• AND THE CHEAPEST INTERVENTION IS HOUSEKEEPING. Keep mulch and soil offthe base, keep sprinklers pointed away, and touch up chips as they appear rather than at the nextrepaint.

Five colours on a spare part order to the post, not to the range

Beige, black, burgundy, green and white, applied to order. ORDER THE COLOUR OF THE POST IT IS GOING UNDER, NOT THE COLOUR THE RANGE WAS SPECIFIEDIN. On a property lit ten years ago those may differ posts get replacedindividually, and finishes get changed. AND EXPECT A NEW BASE TO BE BRIGHTER THAN THEWEATHERED POST ABOVE IT. Powder coat fades outdoors; a fresh base under a six-year-oldcolumn will not match exactly, and at ground level that is usually acceptable where it would not be atlantern height. If the match matters, ask us about refinishing the column at the sametime.

Confirm it suits your post before ordering

This base suits the traditional exterior range, which spans severalfamilies. Traditional is a range description rather than a partnumber, so it is worth confirming rather than assuming. THE RELIABLE IDENTIFIER IS THE GT CODE ON THE ORIGINAL FITTING, plus the column’s outsidediameter and its thread. Measure the column where it meets the existing base and send usthe figure. On a made-to-order part a wrong assumption costs ten business days as wellas the price, and a post cannot stand while you wait.

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

No voltage, no wattage, no IP rating, no lamp base. A POST BASE ISSTRUCTURAL, NOT ELECTRICAL the cable passes through it, but the base itself has no electricalparts. It correctly publishes only a warranty. That is unusual here: 83 of 104 passive parts in this catalogue carry anelectrical field they cannot have. An absent specification on a structural part is theright answer.

Made to order

Allow up to 10 business days for production. A failed base cannot wait tendays standing up. If a post is already unstable, take it down and make the position saferather than propping it and tell us at the time of ordering, because we may be able to advise on aninterim.

What is published

Where it works

• Saving a post whose column and lanterns are sound.
• Corroded ground-level failures the commonest kind.
• Keeping an original column and its patina.
• Not ordered on the range name alone confirm the code and thread.
• Not a householder job the post must come down.

Specifying it

Post base complete with thread, to suit the traditional exterior range. Aluminium, five coloursapplied to order. No electrical parts. Made to order, up to 10 business days. 1-year warranty. THIS IS THE PART THAT CARRIES THE LOAD the column, the arms, the lanterns and their lamps alltransfer their weight and wind load through it to the footing, which makes it the one component whosefailure takes the whole fitting down. A cracked diffuser is a repair; a failed base is a post lying acrossa driveway. IT SITS AT GROUND LEVEL, THE HARSHEST POSITION ON THE FITTING: water runs down the columnand stops there, mulch banked against it holds that water in contact, fertiliser salts attack aluminium andits coating, and every mower strike is a chip where corrosion starts under the powder coat. INSPECT THEBOTTOM 300 mm, NOT THE LANTERN.

Questions

Why does the base matter more than the other parts?

Because everything else is supported by it. The column, the arms, the lanterns and their lamps all transfer their weight and their wind load through the base to the footing, which makes it the one component whose failure takes the whole fitting down. A cracked diffuser is a repair; a failed base is a post lying across a driveway.

What does “complete with thread” mean?

The base arrives with the threaded connection the column screws into, rather than needing one fitted. That makes it a like-for-like replacement rather than a fabrication job.

Can I fit it myself?

It is not a lantern swap. The post has to come down, which means the cable disconnected at the base and the fitting supported while the new base is set. Treat it as an electrician-plus-labour job.

Why do bases fail?

Position. The base sits at ground level, the harshest place on the whole fitting. Rain runs down the column and stops there, and mulch or soil banked against it holds that water in contact. Irrigation and fertiliser reach it, and fertiliser salts are aggressive to aluminium and its coating. And mowers and edgers hit it each strike is a chip, and a chip is where corrosion starts under the powder coat.

What should I be checking?

The bottom 300mm, not the lantern. Blistering or lifting paint at the base means corrosion is already running underneath. The cheapest intervention is housekeeping: keep mulch and soil off the base, keep sprinklers pointed away, and touch up chips as they appear rather than at the next repaint.

Which colour should I order?

The colour of the post it is going under, not the colour the range was specified in on a property lit ten years ago those may differ, because posts get replaced individually and finishes get changed. And expect a new base to be brighter than the weathered column above it: powder coat fades outdoors. At ground level that is usually acceptable where it would not be at lantern height.

How do I know it fits my post?

Confirm rather than assume. “Traditional exterior range” is a range description rather than a part number, and it spans several families. The reliable identifiers are the GT code on the original fitting plus the column’s outside diameter and its thread measure the column where it meets the existing base and send us the figure. On a made-to-order part a wrong assumption costs ten business days as well as the price, and a post cannot stand while you wait.
