Garlok Safety Latch - Garmin Echomap Ultra Tamper Resistant Latch.Works with Garmin Echomap Ultra 102SV, 106SV, 122SV, 126SVThe Garlok is designed to fit snug around the Garmin Echomap Ultra cradle latch, preventing accidental disengagement of the unit from the cradle. A tamper resistant stainless steel torx screw is used to make removal of the latch more difficult without the proper tool. A brass threaded insert is also molded into the latch to provide a tight secure fit.  A T20 tamper resistant torx bit and an extra torx screw are included with each latch. The Garlock latch is made of PETG (Polyethylene terephthalate glycol). PETG is ideal for outdoor use due to its strength and durability. PETG can withstand high temperatures and UV radiation without degrading, making it perfect for applications in hot climates. PETG is also water-resistant, so that it can be used in damp or wet environments without fear of degradation.
