Half-width swivel height restrictor for narrow entrancesThe Half-Width Swivel Height Restrictor uses a single upright post to support a diagonal-braced crossbar, so it protects a gap without needing a matching post on the far side. The crossbar swivels clear on its chain for tall-vehicle access, then locks back down for day-to-day use.Key features Single-post design - one upright post supports the crossbar, useful where there is no room or fixing point for a second post. Swivel crossbar - pivots out on its chain to let a tall vehicle through, then locks back into place. Lockable - secured with a padlock (included) through the locking pin, or a factory-fitted 11mm triangle-key lock. Reflective bands - red and white reflective panels along the post and crossbar for visibility in low light. Galvanised steel frame - lacquered white finish for a durable, weather-resistant build. Two spans, three heights - choose a 2.5m-3.5m or 3.5m-6m span, each available at 1.9m-2.5m, 2.5m-3.5m or 3.5m-3.7m clearance height.
