The blocks are sized to match the firebox opening exactly, creating a solid, level base for the damper. A properly installed damper is required for every indoor Mason-Lite fireplace application.\u003c\/p\u003e\n\u003cp bis_size='{\"x\":11,\"y\":196,\"w\":684,\"h\":137,\"abs_x\":437,\"abs_y\":454}'\u003eClosing the damper when the fire is out reduces heat loss, improves home energy efficiency and keeps drafts out of your living space. Mason-Lite offers several damper o\u003cimg\u003eptions, including anchor plate dampers for masonry or metal chimneys and cast iron dampers with damper blocks, so you can choose the right solution for your venting system. Note that when Mason-Lite firebrick panels are installed, damper blocks are typically not needed. Choosing genuine Mason-Lite parts keeps your installation consistent with the manufacturer's tested system, protecting performance, appearance and long-term reliability. Pair it with other Mason-Lite fireboxes, chimney components and accessories to complete a durable, great-looking fireplace system.\u003c\/p\u003e\n\u003ch3 bis_size='{\"x\":11,\"y\":349,\"w\":684,\"h\":22,\"abs_x\":437,\"abs_y\":607}'\u003eWhat's Included\u003c\/h3\u003e\n\u003cul bis_size='{\"x\":11,\"y\":386,\"w\":684,\"h\":19,\"abs_x\":437,\"abs_y\":644}'\u003e\n\u003cli bis_size='{\"x\":51,\"y\":386,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":644}'\u003eDamper Block\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 bis_size='{\"x\":11,\"y\":420,\"w\":684,\"h\":22,\"abs_x\":437,\"abs_y\":678}'\u003eKey Features\u003c\/h3\u003e\n\u003cul bis_size='{\"x\":11,\"y\":456,\"w\":684,\"h\":137,\"abs_x\":437,\"abs_y\":714}'\u003e\n\u003cli bis_size='{\"x\":51,\"y\":456,\"w\":644,\"h\":39,\"abs_x\":477,\"abs_y\":714}'\u003eComes as three masonry blocks that are designed to lift a traditional vestal damper to fit standard Mason-Lite Masonry Fireplaces\u003c\/li\u003e\n\u003cli bis_size='{\"x\":51,\"y\":496,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":754}'\u003eNote: if using Mason-Lite Firebrick Panels, Damper Blocks are not needed\u003c\/li\u003e\n\u003cli bis_size='{\"x\":51,\"y\":515,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":773}'\u003ePrecision pre-cast masonry blocks\u003c\/li\u003e\n\u003cli bis_size='{\"x\":51,\"y\":535,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":793}'\u003eSupports a traditional damper at the correct height\u003c\/li\u003e\n\u003cli bis_size='{\"x\":51,\"y\":554,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":812}'\u003eSized for the matching Mason-Lite firebox\u003c\/li\u003e\n\u003cli bis_size='{\"x\":51,\"y\":574,\"w\":644,\"h\":19,\"abs_x\":477,\"abs_y\":832}'\u003eInstalls with high-temperature mortar\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 bis_size='{\"x\":11,\"y\":608,\"w\":684,\"h\":22,\"abs_x\":437,\"abs_y\":866}'\u003eSpecifications\u003c\/h3\u003e\n\u003ctable bis_size='{\"x\":11,\"y\":641,\"w\":684,\"h\":206,\"abs_x\":437,\"abs_y\":899}'\u003e\n\u003ctbody bis_size='{\"x\":14,\"y\":644,\"w\":679,\"h\":201,\"abs_x\":440,\"abs_y\":902}'\u003e\n\u003ctr bis_size='{\"x\":14,\"y\":644,\"w\":679,\"h\":24,\"abs_x\":440,\"abs_y\":902}'\u003e\n\u003cth style=\"text-align: left;
