Cuplock horizontals, which include ledgers and transoms, are designed for strength, durability, and easy installation. Manufactured from 40 mm NB tubes, they require virtually no maintenance. Each horizontal tube features forged blade ends that fit securely into the cup of a vertical tube, ensuring a rigid and stable assembly. These horizontals can also be used as guardrails in staircase towers. With a minimum projection of blades to prevent handling damage and uniform dimensions for a precise fit, they deliver both safety and reliability.
