Fundamental Tool Guidelines

The 1797B stripping tool can cover a wide variety of bonded pairs,

and the proper slot selection can be made quickly and accurately,

without knowing the insulated conductors’ dimensions.

The 1797B utility tool is designed

to hold a Bonded Pair in slot A, B or

C such that the WIDTH of the two

bonded wires ideally just touches

the edges of the slot’s major WIDTH

(see diagram). When the two identical

sized bonded wires are placed in the

selected slot, the splicing blade is centered between the pairs, and

separates the bond when the pairs are pushed through the tool.

To nd the most ideally centered blade position, use the largest slot

“C” to hold a short tip of the pair being separated. Untwist the pair by

rotating the tool opposite the pair lay. Once a small section length of

bonded pair is untwisted, place the pair in each slot; A, B and C, until

the smallest slot width is found that the pair will pass through. DO

NOT try to force the pair through a slot that is too small as the pair will

bend, but select the smallest slot that receives the width of the pair.

Selecting the smallest slot possible ensures the blade is centered

between the two bonded insulated conductors, and will allow the pair

to pass through freely under pressure.

Using this untwist / size technique the ideal slot width; A, B or C can

be quickly identied for any bonded pair cable.

Tool Instructions

Pair Preparation—Pick Method, Figures 3 & 4

Lay each twisted pair into the tool channel with the pair ends facing

toward the pick. Place your thumb on the thumb notch to stabilize and

secure the pair. The tip of the pick should rest in the webbing between

the two conductors. While holding the pair in place with your thumb,

puncture the pair webbing with the pick.

Holding the cable in one hand, and the tool in the other, pull the tool

away from you, allowing the pick to separate the conductors of the

pair.

Pair Preparation—Blade Slot Method, Figure 2

Determine which blade slot to use by either referencing the Blade Slot

Selection Table (use QR code or link on the back of this brochure to

access the table) or locate the best t of the pair to the available slots

(see back page).

Insert each twisted pair into the appropriate slot. Rotate the tool or

the pair in the direction opposite of the twist to prevent stripping the

conductor insulation. Continue insertion to match the desire length of

untwisted section. The EDGE of the strip SLOT is designed to provide

a TIA approved separation length (see blue pair example in Figure 2).

Figure 2

NOTE: TIA-568-C.2 allows a maximum of 0.5 inch of untwisted

section after termination.

Jacket Removal—Figure 1

Insert cable into the cutting area and rotate tool at least one

complete turn. Remove the jacket end.

MediaTwist®: Score the printed top and both sides of the cable with

scissors or the Cable Preparation Tool. Then snap the cable from side

to side to complete jacket separation.
