UPHOLESPIDER with Ribbed Head
The Ribbed Head UPHOLESPIDER is used to help track primer true within the hole when up hole loading in broken ground. The reinforced legs and recessed slots make the spider fasten tightly and keep the primer up hole during explosive pumping. The purposely shaped ribbed missile head ensures that the primer tracks true up the hole and does not get caught up where there is bad ground or shears. This helps increase operator safety and protects leads and primer. The product suits all 250g primers and ensures safe deployment and unrestricted passage in holes from 64 – 102mm.
