Stand refurbishment kit

This stand renovation kit consists of a non-standardized, untested chain and a Rapidgied with EN 959 standard. This means that it is perfect for “private” belay station refurbishment. For liability reasons, we strongly recommend that climbing garden owners only use “standardized” kits.

The kit consists of the following three parts. Firstly, a 17cm long round steel chain long link made of AISI 316 / A4 steel. Secondly, two pieces of 8mm quick links made of A2 / AISI 304 steel.

Consequently, this kit fits perfectly with all standard lower off climbing anchors made from this steel quality. With a total length of 32cm, we take into account the tear-out cone for up to 11cm long expansion bolt. We calculate: 17cm chain plus two x 7.5cm quick link = 32cm.

You can find more information on the tear-out cone in our technical article“What do expansion bolt hold?”

Stand renovation

This stand renovation kit makes stand renovation a breeze. You don’t have to remove the old bolt hanger or glue in bolt. This saves an enormous amount of time! Simply hang the chain between the fixed points without tension using the two matching quick links.

Avoid galvanic corrosion

This stand refurbishment kit is made of AISI 316 or AISI 304 steel. I.e. stainless steel. It is therefore intended for use with A4 steel / AISI 316 glue in bolt or bolt hanger. Unfortunately, it results in galvanic corrosion (contact corrosion) with zinc plated components.

This is because combining precious and non-precious components causes this undesirable type of “rusting”.

For more information, read our technical article“Galvanic corrosion at expansion bolt“.

Stand renovation kit standardized correct storage

Store these components dry and separate from other steel parts. In addition, make sure to include information that the chain is made of A4 steel. This is the only way to know which steel quality can be used for a long time afterwards.
