The wall strap tensioner includes first and second links pivotally connected together. A fastener is secured to each of the first and second links for engaging and fastening to the wall strap. Disposed about the opposite end of the tensioner is a flexible cable adapted to be secured to a portion of the metal wall. A connector connects to the flexible cable and a handle is pivotally connected to the connector and movable between first and second positions. A connecting link extends between the first and second links and the handle, the connecting link including third and fourth links that are movable with respect to each other and which are movable between retracted and extended positions. A spring extends around the third and fourth links and biases the third and fourth links towards an extended position. ## Claims ### Claim 1 A method of tensioning a wall strap on a metal wall with a tensioner, comprising: a. securing a first wall strap portion to a first portion of the metal wall; b. mounting a tensioner by: i. attaching a first portion of the tensioner to the wall strap and ii. attaching a second portion of the tensioner, which is spaced from the first portion of the tensioner by a distance, to an anchoring structure; c. tensioning the wall strap by reducing the distance between the first and second portions of the tensioner; d. after tensioning the wall strap, securing the wall strap to a second portion of the metal wall that is spaced from the first portion of the metal wall; e. after securing the wall strap to the second portion of the metal wall, disengaging the tensioner by: i. detaching the first portion of the tensioner from the wall strap, and ii. detaching the second portion of the tensioner from the anchoring structure; f. leaving the wall strap tensioned and secured to both the first and second portions of the metal wall after disengaging the tensioner. ### Claim 2 (depends on 1) The method of claim 1 wherein the anchoring structure includes a corner area portion of the metal wall. ### Claim 3 (depends on 2) The method of claim 2 wherein the corner area portion of the metal wall includes a structure having a series of openings formed therein and wherein attaching the second portion of the tensioner includes connecting the tensioner to the openings in the corner area of the metal wall. ### Claim 4 (depends on 1) The method of claim 1 wherein reducing the distance between the first and second positions of the tensioner includes actuating the tensioner by moving a handle from a first position to a second position. ### Claim 5 (depends on 1) The method of claim 1 wherein the second portion of the tensioner includes a cable, and wherein the method includes connecting the cable to the anchoring structure. ### Claim 6 (depends on 5) The method of claim 5 including connecting the cable to the anchoring structure includes securing the cable to openings in a plate comprised in the anchoring structure. ### Claim 7 (depends on 1) The method of claim 1 wherein attaching a first portion of the tensioner to the wall strap includes utilizing two fasteners that engage and pinch the strap. ### Claim 8 (depends on 1) The method of claim 1 including collapsing the tensioner and utilizing a spring to bias against the tensioner being collapsed. ### Claim 9 (depends on 1) The method of claim 1 including a cable that attaches to the metal wall and wherein the tensioner includes first and second links that include fasteners for attaching to the wall strap; and wherein reducing the distance between the first and second positions of the tensioner includes shortening the tensioner by moving a handle from a first position to a second position. ### Claim 10 (depends on 1) The method of claim 1 including attaching the first portion of the tensioner to the wall strap by securing fasteners to the wall strap and to first and second links disposed about the first portion of the tensioner; and attaching the second portion of the tensioner to the anchoring structure by connecting two ends of a flexible cable that is included on the tensioner to the anchoring structure. ### Claim 11 (depends on 10) The method of claim 10 including reducing the distance between the first and second portions of the-tensioner by moving a handle from a first position to a second position, and moving a connecting link that extends between the cable and the first and second links toward the anchoring structure. ### Claim 12 (depends on 1) The method of claim 1 wherein the tensioner includes a compound linkage having first and second end portions; one or more fasteners disposed on the first end portion for fastening to the metal strap; the second end portion including one or more connectors for connecting the compound linkage to the anchoring structure; the compound linkage being movable between a retracted and extended position; and an actuator for moving the connecting linkage such that a spacing between the fasteners disposed on the first end portion of the tensioner and the connector disposed on the second end portion of the tensioner is reduced. ### Claim 13 (depends on 10) The method of claim 10 wherein the anchoring structure includes a corner area portion of the metal wall, and wherein connecting the two ends of the flexible cable to the anchoring structure includes connecting the two ends to openings formed in the corner area portion of the metal wall. ### Claim 14 A method of tensioning a wall strap of a metal wall with a tensioner, comprising: a. attaching one portion of the tensioner to the wall strap; b. attaching a second portion of the tensioner to a portion of the metal wall other than the strap; c. shortening the effective length of the tensioner by shortening the distance between where the first portion of the tensioner attaches to the wall strap and where the second portion of the tensioner attaches to the metal wall, thereby tensioning the wall strap; and d. after tensioning the wall strap, securing the wall strap to the metal wall; e. wherein the second portion of the tensioner is secured to a corner area portion of the metal wall; and f. wherein the corner portion of the metal wall includes a structure having a series of openings formed therein and wherein the second portion of the tensioner is connected to the openings in the corner area of the metal wall. ### Claim 15 A method of tensioning a wall strap of a metal wall with a tensioner, comprising: a. attaching one portion of the tensioner to the wall strap; b. attaching a second portion of the tensioner to a portion of the metal wall other than the strap; c. shortening the effective length of the tensioner by shortening the distance between where the first portion of the tensioner attaches to the wall strap and where the second portion of the tensioner attaches to the metal wall, thereby tensioning the wall strap; and d. after tensioning the wall strap, securing the wall strap to the metal wall; e. wherein the tensioner includes first and second links disposed about one end portion of the tensioner and a flexible cable disposed about the other end of the tensioner; and wherein the cable includes two ends that are attached to a corner area of the metal wall while fasteners secured to the first and second links are secured to the strap. ### Claim 16 (depends on 15) The method of claim 15 including a handle and a connecting link that extends between the first and second links and the cable, and wherein the method entails moving the handle from a first position to a second position which causes the connecting link to be moved toward the corner area of the metal wall where the cable is connected thereto, thereby decreasing the effective link of the tensioner and tensioning the strap in the process. ### Claim 17 (depends on 16) The method of claim 16 wherein the tensioner includes a compound linkage having first and second end portions; one or more fasteners disposed on the first end portion for fastening to the metal strap; the second end portion including one or more connectors for connecting the compound linkage to a structure other than the strap; the compound linkage being movable between a retracted and extended position; and an actuator for moving the connecting linkage such that the distance between the fasteners disposed on the first end portion of the tensioner and the connector disposed on the second end portion of the tensioner is reduced.
