Rubber Projectiles | Cal Missile Duct Projectiles | Pneumatic Line Carriers
Rubber Projectiles | Cal Missile Duct Projectiles | Pneumatic Line Carriers — Product Overview
Rubber Projectiles (Cal Am’s Cal Missile™ duct projectiles) are engineered to pneumatically run pull-lines through raceways for fast, reliable installation. Built for exposed and underground conduit applications, they blow efficiently through long runs and even out-of-round duct, helping crews pull mule tape and prep conduit for cable installs.
Each Cal Missile features a highly engineered polymer body with two or three polyurethane cups for smooth, low-friction travel and long service life. The cups are designed to resist solvents, oxygen, ozone, and sunlight for outstanding durability. Dual fastening rings (one on each end) create versatile tie-points for mule tape or pull lines, and make for an easy pull-back when needed.
Also referred to as: Dart Blowers, Duct Projectile, Line Carriers, Conduit Carriers, Torpedoes, Parachutes, Darts
Note: Only specific sizes are optimized for SDR 11 duct (marked in the table below). All other sizes are standard duct projectiles.
Key Features & Benefits
- Fast Pneumatic Pull-Line Runs – Efficient for long duct runs and out-of-round pathways.
- Durable Rubber Cone Design – Flexible cones built for many repeated uses.
- Ultra Tough & Tear Resistant – Built to outlast typical line carriers in demanding conditions.
- Secure Tie-Off Points – Dual fastening rings provide reliable mule-tape and pull-line attachment.
- Weather & Chemical Resistance – Polyurethane cups resist solvents, oxygen, ozone, and sunlight.
- Easy Pull-Back – Designed for smooth retrieval and repeat use.
- Multiple Sizes Available – Trade sizes from 1" through 8" to match common duct/conduit IDs.
Ideal for telecom, electrical, and utility contractors, these Rubber Projectiles / Cal Missile duct projectiles deliver clean, predictable performance when installing mule tape, running pull-lines, or clearing duct prior to cable placement.
