Although fixing bolt on holds may seem straight forward it is worth noting a few basic points

It is beyond the scope of these instructions to include information on safe working practice, such as rope access or Health and Safety issues. Nor does it include information on creative route setting but only how to attach the bolt on holds to the climbing wall.

Ideally the whole of the base of the hold should be in contact with the climbing surface. If the hold is too big for the chosen site and rides up on the surrounding surface feature, there is a possibility of breaking the hold due to the point loading when it is tightened. Also on curved walls, if not enough of the base is in contact with the climbing surface, the hold could spin when loaded. It is therefore essential that great care is taken to select the correct size hold for the chosen location.

The vast majority of holds produced by Bendcrete require M10 countersunk fixing bolts and these require fixing to an internally threaded M10 sleeve. On plywood climbing walls these are usually a Pronged "T" Nut. The length of bolt will depend on the type of wall being fixed to. The maximum fixing depth of the holds themselves is approximately 25mm, and a 6mm Allen key is required to tighten the bolts. The bolt must be threaded into the fixing sleeve by at least 10mm. The easiest way to ensure this is to place a bolt into the hold and with the bolt firmly pushed all the way into the hold present it to the fixing hole until it makes contact with the fixing sleeve. The distance between the climbing wall and the back of the climbing wall should then be at least 10mm. Most bolts over 40mm in length have an unthreaded 'shoulder', on no account must this part of the bolt be screwed into the fixing sleeve as it may become damaged.

Some of the larger holds also have an additional fixing hole designed to accept a woodscrew fixing. This is to prevent the hold from spinning but can only be used on plywood based walls. Some holds and features also rely solely on wood screw fixings. These are indicated in the relevant section. Bolts should be screwed in until the hold becomes tight and then slowly tightened a further half turn. This should be sufficient to secure the hold. However, if it still rotates, the bolt should be tightened a further quarter to half turn. Repeat this procedure until the bolt on hold is tightened. DO NOT OVER TIGHTEN HOLDS AS THEY CAN BREAK AND REMEMBER EVEN THE BEST FITTED HOLDS CAN SPIN
