Prima Heavy Duty Tubular Latches

Prima Heavy Duty Tubular Latches are designed for use with internal door handles, providing a strong, smooth-operating latch mechanism for everyday doors in busy settings. The range includes fire rated options and comes in multiple size and finish choices, depending on the version selected.

Sizes, backset options and finishes

Choose from three latch case sizes across the family: 76mm, 102mm and 127mm. For simpler specification, some versions list their backset alongside the case size, including a 57mm backset on the 76mm latch and an 82mm backset on the 102mm latch.

Finish options vary by size, with choices across the range including warm metallic tones such as Antique Brass, contemporary options like Matt Black, and brighter plated looks including Polished Chrome. Some variants are also offered in Satin Brass and a mixed Electro Brass and Chrome option.
