Search for Triax 300721 on amazon. Not cheap though.
That metal LNB clamp looks a far better design than the original, and you don't have to remove the whole clamp just to change the LNB - If the plastic clamp on my TD110 should ever break (as has happened before) then I'll think about getting one of those.

Hi jeallen01. Yes, my grey clamp takes a nut and bolt as you describe. It also has the lugs which spring out once you've put the clamp INSIDE the arm.

In that case, have you checked if putting the bolt and nut in the hole, and tightening them up, does then "close the gap" sufficiently to allow the clamp to be inserted in the arm?

If that doesn't look like it will be successful, then it would appear that you have a poorly-manufactured clamp - at this point, you would have to make a decision, possibly one of the following:
- Take the issue up with the supplier to get a replacement - but that will most likely involve sending the whole dish kit back to him and waiting for a replacement, which would could take a couple of weeks or more, depending on where he is located, AND how quickly he responds to the request (some suppliers are distinctly "better" than others in that area!)
- try modding the existing clamp as you previously suggested and/or possibly removing some plastic from between the arms of the clamp so that they will pull nearer together when the nut & bolt are tightened
- Buy a "standard" Triax replacement clamp kit from ebay, Amazon etc., for about £12-£13 delivered , although some kits are priced at £18- £19 (in both cases, ridiculous prices for a small plastic moulding - bit like one of those old Airfix kits - IMHO!)
- Buy the one that @ozumo identified for about £20, and solve your problems, and "for good" it would seem.

Aye, the bolt will do the job but I dislike things that aren't 'just right'. And forced closure must surely be putting excess pressure on the hooky bit at the top. The ridges inside the ring are why the clamp won't close properly, I reckon. They're there for grip but I'm sure there'd still be plenty of grip if I rubbed down one side, possibly both.

l'll get it up and running, no bother, but the aluminium version will be on my Christmas list...

Out of curiosity, if you tighten up the clamp using the nut and bolt, but out of the dish feedarm, what does the LNB aperture diameter measure? Maybe it's designed for a 23mm neck LNB?

The diameter is a tad short of 40mm according to my old school ruler. There's a separate adaptor for a 23mm LNB.

Depending on what part of the holder is defective, a solution like this picture would also be possible:
Or above the plastic part, like this picture: Afgebroken vergrendeling LNB houder

These examples are for the triax multifeed LNB holder.
I remember having seen a solution like this for the standard Triax holder as well, but cannot find that ATM.

Yup, the "hooky bit" at the top is where they break - another aspect of the "less than perfect" design of the dishes in the TD range!:rolleyes:

PS: from my quick look at the Triax site earlier today, it looks like that they may have discontinued the TD110 and possibly also the TD88!

jeallen01 - your Triax dishes: 1 U-bolt or 2? Mine came with one as mentioned earlier but I still think two would be more sensible...

See photos (some bits partially obscured by various "forms of camouflage"!)
TD110 (probably 10yrs old) - 2x U bolts
TD88 (probably 20 yrs old) - 2x U bolts
TD78 (probably 6-7 yrs old) - 1x U bolt

If you want to add extra U bolts you can find them on ebay - maybe not in "sat stuff" areas but take a look at general DIY materials and (seriously!) caravan stuff.

Hi, and many thanks for going to all that trouble. As with your TD88, I also plan to use an extra bolt for fixing the dish to the bit with the degree markings on it.

I've had a look for a suitable pole clamp but with no luck so far. Most say 'up to 2"' but I need a U-bolt with an inner gap of 60mm. A lot of these bolts don't come with the 'jaws' so they're no use. If anyone can point me to the correct size pole clamp, I'd be much obliged.

Exhaust clamps might be what you're looking for, or at least provide the jaw part.

Try something like one of the sizes of these bolts, or something similar, and then get a suitably-sized car exhaust clamp (very useful items for sat dish installations ) to provide the "other half" of the clamp.

For a dish of the size you appear to have got, you won't need a great deal of clamping force, so you won't need anything with serrated jaws like some genuine sat-specific ones.

Great stuff - thanks guys. Not sure about your 'something similar', jeallen01 (flange bolts???) but the exhaust clamp looks good despite it having a smooth grippy bit.

Being in a hurry at that time, I must have posted the wrong link under "something similar" - this was probably what I meant to post about the various types/sizes of "U" bolts (both "round" and "square" types, though the latter take a bit more finding!), so "take your pick" :D

Return the defective dish and buy Gibertini xp 75 as recommend by lovely people on this forum to me when i bought mine its aluminum , super strong Galvanised 2 U bolts clamp , very light weight and
LNB holder in aluminum die-cast inclusive of Allen key. Very easy to tight bolts with hand no tool needed.
looks super cool and strong only £59 on Amazon £9 delivery sold by HM Sat Germany great service from them.
And by the way I am not affiliated with HM sat or Amazon.

The clamp is for the 40mm but is designed for the light grey paint of the dish, as opposed to the anthracite option.

There are almost identical feed clamps available from a different - cheaper - manufacturer, which are made from very soft material. The original, even if snapped will hold the LNB reasonably steady in position (though it is worth securing the cable(s) in position to stop the skew from altering.

I will find a link this weekend.

I don't think it is worth changing the Triax, like Fracarro dishes once they are up and running they don't require any further maintenance. The smaller diameter models however arrive complete with exceedingly sharp edges on the support parts, and you have to be really careful when assembling them.

Bit confused what kind of maintenance required for already super strong Gibertini xp dish
