{"title":"Manhole inspection systems","description":"\u003cp\u003eKetta is the New Zealand distributor of SAM manhole inspection grates.\u003cbr\u003eThe SAM circular safety grate by Mass Products is a temporary fall protection safety device designed to be used during maintenance in and around manhole openings.\u003cbr\u003eThe Mass Products SAM Manhole Safety Grate was developed because of a need for increased safety around open manholes. \u003cbr\u003eIt is widely known in the industry that opening a manhole can be a potentially high risk and fatal activity that requires operators to erect approved safety equipment. \u003cbr\u003eIt is impractical and inefficient to erect and remove, in typical situations, safety barricades each time a manhole is needed to be inspected or maintenance to be carried out.\u003cbr\u003eWe have developed Mass Safety Grates to reduce and eliminate those safety issues. \u003cbr\u003e\u003c\/p\u003e","products":[{"product_id":"sam-c1-r45-circular-safety-grate-suits-550-to-650-mm-manhole-with-45-mm-nylon-roller","title":"SAM C1-R45 circular non-folding safety
