Ragni rubberised corner blocks, which feature specially designed gripping zones and have an increased surface area to maintain a strong purchase and ensure a tight line with no slippage. They are available in 2 Hi-vis colour options (Yellow and Orange), which really stand out on site and prevent loss. They are manufactured from TPR recyclable rubberised plastic and are soft to the touch. The flexibility also assists the purchase of the block, with them flexing to gain a stronger hold. These blocks allow the user to span long lengths of brickwork with maximum tension, which ensures a tight line and more accurate laying. They are often used in conjunction with Ragni brick line and line pins.
