Carl F Groupco has expanded its hardware inventory with the introduction of the new patented release and turn (RT) handle by J Banks & Co.

The new lockable RT handle is said to be easy to operate and offers a slim, compact design that doesn’t obstruct internal blinds and fittings.

Designed and manufactured in the UK, the patented handle is suitable for use on aluminium, PVC-U and timber windows and delivers a low stack height of just 16mm. The handle incorporates a slim lock and key release cylinder and fits all espagnolette and shootbolt systems with 43mm hole centres.

Available in various spindle lengths, the RT handle has a comfortable handle grip lever, while its non-handed design delivers product flexibility. It has been designed, tested and manufactured to meet all UK standards of strength and durability.

John Crittenden, MD at Carl F Groupco, said: “The new patented RT handle is a unique concept in window handles and designed in the UK for the British market. The handle incorporates some intelligent design features and is available in a range of durable powder coated and plated finishes with diecast colour matched screw covers supplied for next level aesthetics.”
