The working tolerance is created by the

curvature of the bend on the J bolt. Apollo hooks have a 11mm radius that

provides a working tolerance of 22 mm which is the maximum allowable distance between

the actual position of the drilled hole and the

ideal position of where the hole should have been drilled.

The ‘arrow’ point provides no more than 3 mm of working tolerance.

Any connection on the straight part after the bend, indicated by the ARROW will lead to a maximum load of no more than 10 kN before they bend.

That’s a SWL of only 5 kN MAX We know because we had independent tests carried out.

So the safe working load is no more than 5 kN. This is why some other suppliers state a safe working load for their hooks

of only 3.5kN. Apollo’s are 18.3 kN: Quality performing designs

The Apollo plugs are dimensionally correct and system

compatible. Lengths are: 70, 100, 135 and 185 mm

Manufactured from PA6 nylon

The plug has a collar to assist in the correct and

optimum setting and to retain the plug as being ‘surface fixed’. Like its designed to do!

The imitations may be labelled 70 mm when in fact

they are 75 mm. How deceitful but very true!!!

They probably will not have a collar.

Maybe plastic and not PA6 nylon. Plastic

deteriorates by collapsing up to 2 mm within 4 weeks after the installation has been loaded.

You should never accept a 75 mm plug as being system compatible. The extra 5 mm of plug length

reduces the area of expansion by 10% so it must have an effect on performance. If a 70 mm plug is not necessary then why are setting rings positioned for 70 mm plugs? Remember the correct installation is

achieved when the screw protrudes past the end of the plug by 6-8 mm. How does this enhance performance by a significant amount? Please call us and we will advise!

We have a potential concern about professionalism within our area of the construction market.

The suppliers of the 75 mm plugs either know that it is non system compatible and are therefore deceiving customers or if they don't know about the system needing to be compatible by design and dimensions it

means their technical application knowledge needs to be questioned.

Other types are not likely to provide you with

the optimum performance as they are not system compatible.

TG4:11 recommends compatible systems.

The tooling to produce an ‘Apollo

Hook’ costs more than other designs and also needs to be

replaced on a regular basis to maintain a close to parallel as

possible on the return leg of the ‘J’ bolt. This design is performance

enhancing and allows a safe working load of 18.3 kN
