Cap45® is an isolation cap/bar that snaps onto the front of the pass-through RJ45 plug after termination covering the exposed wire’s ends. Cap45® prevents electrical shorting in the RJ45 mod socket due to improperly trimmed wire ends touching the socket walls.
With other brands pass-through RJ45 mod plugs, there is a risk that the wire ends after termination are not correctly trimmed flush to the plug. This risk is why some manufacturer brands discourage the use of pass-through RJ45s and some network systems cannot be certified if using pass-through plugs.
With Simply45® ProSeries’ Cap45® these risks are eliminated. That is why Simply45 ProSeries Pass Through RJ45 Modular Plugs are the recommended pass-through plugs for commercial applications, HDBaseT, PoE/PoH, and all commercial & residential certified systems.
