There is the step of unwinding wire from the wire spool 12.

(18) In the operation of the preferred embodiment, several features have been added to a stepladder to assist electricians.

(19) Conduit Holder 3

(20) When an electrician wants to cut a piece of conduit, he braces the conduit with his knee between the rivet heads on the third step from the bottom. The new integrated conduit holder secures the conduit between the conduit holder hooks and the protective rail shield for easy and safer cutting.

(21) Hacksaw Hook 7

(22) Electricians will tape or screw hooks onto the outside of their ladder rail to holder their hacksaws when not in use. These hooks are often mounted on the outside of the rail. They will then hang heavy tool belts and buckets that could tip the ladder over. The integrated hacksaw hook is placed in the inside of the frame on the center of the step of the ladder so not to create a tipping hazard and is firmly secured to the step.

(23) Wire Spool Holder 4

(24) When a stepladder is used as a wire caddy the users will rest the conduit on the top of the front step and through the top of the rear horizontal. This allows the conduit to move when the wire is being used, and is not level. The new integrated wire spool holder provides adequate support for conduit while keeping the conduit in place and level.

(25) The Electrician's Jobstation is a new ladder design based off of the IAA platform. There are four new and innovative features that make up the new design. The new design has a plastic top 1, as shown in FIG. 1, with features designed to benefit an electrician, a conduit holder 3 with side shields 5, a hacksaw hook 2, and two sets of wire spool holders 4. See U.S. patent application Ser. No. 11/347,613, incorporated by reference herein.

(26) The top 1 has many new features designed especially for the electrician. The top 1 has screw driver holes a hammer/drill holster. The top also features slots for channel locks, side cutters, pliers, and wire strippers. Each of the features has a raised icon next to it for easy identification.

(27) The conduit holder 3, as shown in FIG. 2, is designed to hold various sizes of conduit 6 up to one inch in diameter. FIG. 3 shows the conduit holder 3 with the hooks 7 in the retracted resting position. FIG. 4 shows the conduit holder 3 in the open position. The hooks are connected by a bar 8 and are mounted to the side rails of the ladder 10 with the mounting brackets 9. The bar 8 allows the user to operate both hooks 7 with one hand. This one handed operation allows for safer handling of materials and tools. Attached to the rail 10 are side shields 5. The side shields protect the rail 10 from being damaged by the conduit 6 or an errant cut by a hacksaw. To use the conduit holder 3, the user has to pull the hooks 7 toward himself and then place the conduit 6 in the hooks 7 (See FIG. 2). The conduit 6 then rests on the rail shields 5. Once the conduit 6 is pulled out of the hooks 7, the hooks 7 they will retract.

(28) Mounted on the rear of the front step 11, as shown in FIG. 3, is the hacksaw hook 2. This hook 2 is mounted on the rear of the same step 11 as the conduit holder 7. After the user is finished cutting the conduit 6, as shown in FIG. 2, he can hang the hacksaw on the hook 2 and retrieve another piece of conduit 6 to cut.

(29) The wire spool holders 4, as shown in FIG. 5, are mounted on the front step 11 and on the rear horizontal 13. The wire spools 12 are placed onto the conduit 6 before they are inserted thru one of the spool holders 4 and then through the one opposite. The spool holders 4 are mounted so that the conduit 6 is level and the wire spools do not all shift to one side of the ladder and bind.

(30) The conduit holder 3 is further described in FIGS. 6 and 7. The hooks 7 are welded to the bar 8 which makes them move together. The pivot point 14 attaches the hooks 7 to the rail 10. The user will grab the hook 7 and pull it towards himself. The handle 21 on hook 7 is not necessary but aids the user in gripping the hook 7. The spring 15 automatically retracts the whole assembly when the user is done.

(31) The conduit holder is limited by the step 11, as shown in FIG. 2. The front of the step 11 will stop the holder when it is coming forward and the rear of step 11 will stop it when it retracts.

(32) The recommend weight limit for the wire spool holders 4 is 375 lbs, (the same as the duty rating of the ladder).

(33) The hacksaw hook 2 is meant to hold a hacksaw and is labeled as such. It was designed to hold 250 lbs in cases of accidental overloading.

(34) Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
