Full Product Overview
The Lyte Fibreglass Triple Extension Ladders (STGRP3) are professional-grade extension ladders engineered for trade users who require extended working height alongside dependable electrical insulation. Constructed from non-conductive fibreglass (GRP) side stiles with durable aluminium rungs, these ladders are particularly suited to electricians, engineers, utility contractors and maintenance professionals working near live electrical systems.
Certified to EN131 Professional standards, the triple-section design provides working heights up to 7.3 m while still retracting to a more manageable stored size for transport and storage. The robust GRP construction resists corrosion, weathering and warping, making the ladder suitable for demanding indoor and outdoor environments.
Slip-resistant D-shaped rungs offer improved climbing comfort and secure footing compared with traditional square rung designs, helping reduce fatigue during repeated climbs. A stabiliser bar improves overall base stability and reduces sideways movement, while the manual thumb-operated locking system allows controlled, secure extension adjustment on site.
Designed for regular professional use, the STGRP3 range combines electrical safety, structural durability and dependable trade performance in one versatile extension ladder system.
