RIBBED HEAD SPIDER
The MTi Group RIBBED HEAD SPIDER is specifically designed to help track primer true within the hole when up hole loading in broken ground. The reinforced legs recessed slots make the spider fasten tightly and keep the primer up hole during explosive pumping. The ribbed shaped missile head ensures that the primer tracks true up the hole and does not get caught up where there is bad ground or shears. The plastic selected allows a combination of function and durability able to withstand impact whilst being rigid enough to hold tightly onto primers.
