Designed as an upgrade to the NAS1637 Adjustable Keeper with Mounting Provisions, this product interfaces with the NAS1637 latch to retain Line Replaceable Units (LRUs) into ARINC 404-style trays. With upgraded materials, finishes, and additional features, it:
|Structural anodized aluminum construction||Minimal concerns for galvanic corrosion compared to the to-spec design.|
|Lockwire holes||Allows for use of .032" diameter lock wire to prevent rotation of assembly when LRU is not installed.|
|Free running screw thread inserts||Greatly improved user experience when adjusting length of product in the field.|
|O-ring||Prevents accidental disassembly of product before it is installed.|
|Large adjustable length||Adjustable range eclipses that of a to-spec NAS1637 adjustable keeper. Screw connecting the mounting block to the Adjustable Keeper has an optimized length to maintain large adjustment range (1.55" – 1.925").|
