CAT6A Junction Box with 110 Punch Down Block | White (SMB001-6AJB)

This is a Cat6A junction box for splicing two Cat6A cables together permanently, without a coupler or a pair of plugs. Inside the white surface-mount housing is a 110-style punch-down block that takes 110 or Krone blades, with the terminals color-coded for T568A and T568B, so the eight conductors of each cable punch down to the same positions and the splice holds Cat6A performance for 10GBASE-T over a 100 m channel. It takes solid 23 to 26 AWG Cat6A, the two cables come in through two entries, and a cover snaps over the block when the work is done. It's sold individually, and it needs a 110 punch-down tool, which isn't included. For joining two terminated patch cords instead of two bare cables, a keystone coupler such as the COU6-SHD in the SMB005-4PWHI box.

Features

• Permanent splice, no connectors. Two Cat6A cables punch down to one block; no plugs, no coupler, nothing to work loose.
• 110 and Krone punch-down. The block takes either blade style.
• Color-coded terminals. T568A and T568B marked, so both cables land the same way.
• Holds Cat6A performance. 10GBASE-T up to 100 m.
• For 23 to 26 AWG Cat6A. Two cable entries.
• Surface mount, white, with cover.
• Sold individually. 110 punch-down tool required, not included.

Where It Fits

It suits structured cabling crews repairing a Cat6A run that was cut by a drill, a rodent, or a renovation and can't be re-pulled, data center and server room techs extending a run that came up short of the new rack location, anyone moving a wall jack a few feet and wanting to reuse the existing cable instead of pulling new, building retrofits where two lengths of Cat6A have to become one inside a ceiling or a closet, network backbone links between closets that were run in two pieces, and a job that already has the bulk Cat6A and the 110 punch-down tool from the copper collections. For a splice that can be undone later, two KEY6-90 or MIG6A-90 keystone jacks and a short patch cord in an SMB005-4PWHI box; for shielded Cat6A, ask us before ordering, since this box's shielding isn't stated.

Good to Know

A punch-down splice is a permanent fix and a good one, but it's still a splice: it adds a connection point that the standard counts as one of the four allowed in a channel, so don't put more than one in a run if you can help it, and keep the total channel under 100 m including the patch cords at both ends. Strip each cable back only as far as it takes to reach the block, keep the twist in each pair to within half an inch of the terminal, and punch both cables down to the same standard, T568A or T568B, matching whatever the jacks at the two ends use; the color coding on the block makes that hard to get wrong but doesn't make it impossible. Use solid-conductor cable; punch-down IDC terminals are made for solid 23 to 26 AWG and won't hold stranded patch cord reliably. Test the full link after the splice with a certifier if the run is Cat6A for 10 Gigabit, since a splice that passes continuity can still fail NEXT at 500 MHz if the untwist is long. Mount the box where it can be reached again, label it on the as-built, and don't bury it in a wall; a splice behind drywall is the one nobody can find in five years. The page doesn't say whether the block is shielded, so for a shielded Cat6A run, confirm before ordering, because an unshielded splice breaks the shield's continuity and the drain wire has nowhere to land.
