The MTi Group RIBBED HEAD SPIDER is specifically designed to keep the primer aligned and true within the borehole during up hole loading, particularly in fractured or unstable ground conditions. Its reinforced support legs with concealed slots allow the spider to lock securely in place, ensuring the primer remains correctly positioned in the up hole while explosives are being pumped. The missile-shaped, ribbed head design enables the primer to travel smoothly and straight up the hole, preventing snagging in poor ground conditions or along shear planes.
Specification / Detail
The plastic material combines functionality and durability, offering strong impact resistance while remaining rigid enough to securely grip the primer.
RIBBED HEAD SPIDER supports safe installation with a clear, unobstructed path in boreholes ranging from 64–102 mm in diameter, reducing the risk of becoming lodged inside the hole. Its reinforced legs are designed to lock the primer in place, preventing movement during the loading process.
