Details

The Keystone HDBOX/K-100 is a heavy duty solid wall box lintel, specifically engineered to support openings in 100mm wide solid masonry walls. Built to handle substantial loads, this lintel is an excellent choice for contractors and site managers working on demanding structural projects where reliability and strength are essential. Please note, the lintel must be bedded on mortar with adequate end bearing for safe use.

Application

This box lintel is commonly used to support structural openings such as windows and doors within 100mm solid walls. It is designed for heavy duty loading conditions and is suitable for carrying the weight of concrete floors and point loads above openings. The perforated design along its length ensures strong adhesion with plaster, helping to deliver a secure and durable finish on site. For best results, lintels should be properly propped during installation to speed up construction without compromising safety.
