These expand the Zircon offering from eight models to eighteen. Zircon is not an all-purpose alternative—no block is. But these smaller sizes make Zircon appropriate for control lines where multi-part purchases are required. Zircon reacts immediately. So, when the pressure gets light and you ease that 24:1 Cunningham rigged under the deck or want to let the jib lead forward for some more power through the chop, you will get response.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"border-collapse:collapse;width:100%;max-width:100%;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eBreaking load (kg)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e480 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eBreaking load (lb)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e1050 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eLength (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e2 1\/8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eLength (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e54 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum line Ø (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e1\/4 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum line Ø (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum working load (kg)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e160 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum working load (lb)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e350 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eSheave Ø (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e1 1\/8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eSheave Ø (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e29 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eWeight (g)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e22.5 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eWeight (oz)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e0.79 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c!-- sr-faq v=1 vendor=harken source_sha256=27499024bcadc12e19062e0055c9491a24560e28653766c9b5d8a37fe9b49d49 --\u003e\u003ch3\u003eFAQs\u003c\/h3\u003e\u003cdetails\u003e\u003csummary\u003eHow often should I clean and maintain the Zircon block?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eClean the block and attachments frequently with detergent and fresh water, flushing bearings and sheave areas while rotating parts.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eAre there mounting safety considerations for the Zircon block?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eDo not lash in line with the seam, as this can split the block and cause failure.
