The Allen High Load Blocks add additional strength (though a stainless steel sheave turned from solid) to Allen's proven A2030Tii blocks to create a complementary product that though slightly heavier than the standard blocks has a higher Maximum Working Load and Breaking Load.;
Allen 30mm Dynamic Blocks use the same high quality dynamic bearing, materials and precision engineering as our 20mm Dynamic Block range. Allen's high strength and rope friendly stainless steel ultra-strap makes them amongst the strongest and most reliable ball bearing blocks in their class.
