9. Series 77 “Full Nelson” Shrink Boots
Rugged, Reliable Environmental Protection
Semi-rigid heat-shrinkable boots offer excellent electrical, mechanical and environmental protection
Rugged, Flame-retardant elastomeric material
Resistant to high temperature and chemicals
Option for NES smoke and toxicity compliance
Straight or right angle
Wide range of sizes and shapes for circular and rectangular connectors
No special tooling required
Heat shrink boots and other molded shapes offer fast and easy protection of terminations and transitions and are a common addition to a wide range of cable construction types including open-loom wire harnesses and backshell equipped jacketed cables.
Made of flame-retardant elastomeric resistant to high temperatures and chemical exposure, boots are produced for both straight and angled cable entries in a wide range of sizes. The range of possible boot shapes is almost limitless and can accommodate both circular and rectangular connectors as well as multi-branch fittings.

16. Overview: Building Commercial Accessory Part Numbers From Scratch
“What backshell part number should I use for this connector?”
Select Series based on main required function
Select “Basic Part Number” based on additional required features
Use the “Connector Designator” to Indicate the series of connector the backshell is for
Select “Angle and Profile based on routing requirements
Flesh out other variables manually or use “QwikCreate” on-line

17. Step (1): Select Series Based on Function
Environmental
Backshell
Strain Relief Clamp
Protective Cover
EMI Banding Backshell
EMI/RFI Backshell

18. (2) Select “Basic Part Number” Based on Additional Requirements/Features
NOTE: Use the Series and Basic Part Number Combination (XXX-XXX) when searching on web

19. (3) Select “Connector Designator” Based on the Connector Series the Part is For
HINT: Just Memorize the Common Designators

20. (4) Select the “Angle and Profile” Based on Cable Routing Requirements
HINT: Again, just memorize the most common codes

21. (5) Select Other Variables Manually or… Use QwikCreate
QwikCreate: Internet-Based Automated Part Number Development
The remaining variables (finish, size, etc.) are all straightforward. Either use the catalog or finish out the part number with QwikCreate:
Generate printable document with all relevant dimensional data
Link to catalog page for additional information
Automatically select for Style 2 cable entry

22. Rectangular Backshells Use The Same System and Logic
MIL-C-24308
MIL-C-81659
MIL-C-83733

23. More Ways to Insure You End Up with the Right Part
Helpful Tips
More Ways to Insure You End Up with the Right Part
Use Part Number Index to Match Part Number and Catalog Page
Use Part Number Reference to Cross MS Numbers to Glenair Commercial Series Parts
Use Glenair.com site search and Product Selection Guides to quickly locate relevant information

24. Importance of Understanding What the Connector Part Numbers Mean Too
Interconnect Components All Go Together
If you can determine the connector series, size and plating….
You can easily match it to an appropriate accessory
But mismatched parts = trouble
Potential for incorrect fit, dissimilar plating, or other problems
