A high-tensile bolt secures the HM-HALO-C into the desired position on the FG-HALO-C central spine, and a 13mm diameter hole in the top of the mount allows attachment of the desired clamping device. HALO Compact User Manual V7 December 2019... -
Page 9: Safety
Do not modify or alter the HALO Compact hardware or accessories, nor use them in any way other than that described in this manual. Rigging components supplied as part of the HALO Compact system are in no way interchangeable and should not be used as such. -
Page 10: Secondary Safeties
Safety Inspections Carefully inspect all flying system components prior to use for defects or signs of damage prior to assembling a HALO Compact array. If any components damaged or you suspect them to be damaged, DO NOT USE THEM. Regular scheduled tests – which are much more rigorous than visual inspections – of all rigging components must also be carried out. -
