Spiders

Pick SLUMPSTOPPA™ when you're loading emulsion into underground upholes and the column won't stay where you put it. Polymer bristles with a stainless steel spine fold on insertion and grip the hole wall — holding the emulsion column in place while the bristles let the gas through normally. Three sizes: 2.5"–3", 3"–4", 4"–4.5" (64–115 mm). The dedicated emulsion-slump solution.

Pick Shot Bags when the hole is wet, cracked, or won't hold a clean column on its own. Empty polypropylene tubes you fill on site with the material the hole needs — ANFO or emulsion to make a bagged charge that won't get diluted by water or lost into cracks, or stemming material (drill cuttings, sand, gravel) to add weight to the column. Eight sizes from 3" × 36" to 8" × 36" (76 – 203 mm × 914 mm). Some sites call them poly bags. Same idea.

Pick BLASTBALL™ when you've got a wet hole, a breakthrough, or cracks and voids that need a reliable seal across an irregular bore. The only inflatable in this collection rated for wet-hole deployment — lower it through water on a drop line, then inflate with compressed air. Reinforced rubber bladder with nylon webbing handles -58°F to 185°F (-50°C to 85°C). Three sizes covering 2.5" to 8" (64 – 203 mm).

Pick a MultiFit Spider when you need the booster centered in the explosive column for even detonation. The spider's flexible legs fold on insertion and extend automatically once it's in the hole, centering the booster and protecting the detonator wire. Two sizes — 150G fits 2.5" – 4.5" holes (64 – 115 mm) and supports lighter boosters; 250G fits the same range and supports heavier boosters. Quick "shotgun-style" load through a 25 ID / 32 OD ANFO hose.

Pick the Booster Lock when you're running pumpable explosives or loading into wet boreholes and the booster wants to float. Clips onto the booster and locks it at the depth you set, so the primer stays where the shot design called for. Fits holes 5" (127 mm) and larger. Simple clip-on design — no inflation, no tools.
